Known Issues for Compute

Details

After restarting a Windows Compute instance, the systems fails to boot and remains stuck on the loading screen.

Workaround

Perform a diagnostic reboot as documented here: Performing a Diagnostic Reboot. A diagnostic reboot stops an instance, rebuilds the instance, and then restarts the instance.

Details

A Windows Compute virtual machine instance boots into the repair dialog after starting. Additional reboots also boot into the repair dialog.

Note

This issue occurs in both shielded and non-shielded instances.

Workaround 1

Perform a diagnostic reboot as documented here: Performing a Diagnostic Reboot. A diagnostic reboot stops an instance, rebuilds the instance, and then restarts the instance.

Workaround 2

If workaround 1 doesn't work, try modifying the instance configuration. For example:

• Change the shape of an instance, see: Changing the Shape of an Instance.
• Change the fault domain, see: Editing the Fault Domain for an Instance

Then, if necessary, repeat workaround 1.

Details

Customers that use Oracle Linux 8 on ARM shapes and run version 1.43.2-18 of Oracle Cloud Agent (OCA) need to restart the updater service on their instances. An OCA updater known issue prevents the updater from polling for future upgrades and a restart resolves the issue.

Workaround

To check the current version of OCA on your instance, run the following command:

yum info oracle-cloud-agent

To restart the updater, run the following command:

sudo systemctl restart oracle-cloud-agent-updater

Details

ClamAV signature marked legitimate binaries as viruses because of a bad signature database (virus definition 26931). This issue caused ClamAV to identify Oracle Cloud Agent and its plugins as viruses. By default, ClamAV doesn't quarantine infected files. Therefore, despite the false detection, the agent and its plugins continue to function normally. Even if a quarantine action was taken on an instance, the agent and plugins remain unaffected and functionalities, like Updater and heartbeat, operate as expected. However, a restart of the agent or instance will break the functionality.

Workaround

If your instance is impacted, see Installing the Oracle Cloud Agent Software to install new package of Oracle Cloud Agent.

Details

An existing limitation in virtual network attachments limits total host network bandwidth to 60 Gbps on BM.Standard.E5.192.

Workaround

No workaround exists. We're working on a software fix that will not impact any live network workloads when deployed.

Details

After you create a compute instance, you cannot enable or disable confidential computing for that instance at a later time.

Workaround

We're working on a resolution.

Details

Confidential computing is not supported on Oracle Linux 9.

Workaround

We're working on a resolution.

Details

On older generation AMD systems, (E2/E3 using AMD Rome processors), a guest using Secure Encrypted Virtualization (SEV) memory encryption (not enabled by default) with more than 350 GB of memory can result in a CPU soft-lockup warning on the host/hypervisor during guest boot/shutdown, due to the time taken to flush the pinned memory being encrypted being proportional to the amount of memory, and with larger amounts of memory in excess of 350 GB the time taken on the CPU is excessive and results in the warning. After the memory is flushed, the hypervisor returns to regular operation.

Newer systems, such as E4 (based on AMD Milan processors), have hardware support that minimizes the time spent flushing the memory so that no CPU soft-hang occurs.

Workaround

If you require an SEV-enabled guest with more than 350 GB of memory, then create it on an E4 system (based on AMD Milan processors). On systems with AMD Rome processors (E2/E3), limit the memory to less than 350 GB, if using SEV memory encryption.

Details

For the following list of Compute shapes, multiple names are used for the same shape.

• BM.GPU.A10.4: The name appears as both BM.GPU.A10.4 and BM.GPU.GU1.4.
• BM.GPU.A100-v2.8: The name appears as both BM.GPU.A100-v2.8 and BM.GPU.GM4.8.
• VM.GPU.A10.1: The name appears as both VM.GPU.A10.1 and VM.GPU.GU1.1.
• VM.GPU.A10.2: The name appears as both VM.GPU.A10.2 and VM.GPU.GU1.2.

Workaround

Disregard the different names. For each shape, the underlying hardware is the same.

Details

When you attempt to connect to an instance on Oracle Cloud Infrastructure using a client running macOS Ventura (version 13) or a client running OpenSSH 9.0, you might encounter connection issues resulting in errors similar to the following:

Unable to negotiate with 192.0.2.181 port 22: no matching host key type found. Their offer: ssh-rsa
kex_exchange_identification: Connection closed by remote host

Workaround

Add the following to the ~/.ssh/config file:

Host *
  PubkeyAcceptedKeyTypes +ssh-rsa
  HostkeyAlgorithms +ssh-rsa

Details

Instances that run the September 2022 platform image for CentOS 7 (image name CentOS-7-2022.09.20-0) lose connection to iSCSI-attached boot volumes after 24 hours. The issue happens because the instance loses its DHCP lease after 24 hours.

Workaround

We recommend that you terminate (delete) any existing instances that use this image, and recreate the instances using a different CentOS 7 platform image.

If you cannot terminate any existing instances that use the September 2022 CentOS 7 platform image, you can obtain a new 24-hour DHCP lease by rebooting the instance.

Details

This issue affects bare metal instances that use previous generation shapes (for the purposes of this known issue, shapes with an end of orderability date before October 2022) and that run Windows Server 2016 Datacenter edition.

When you open the Hyper-V Virtual Switch Manager and try to create a new external virtual switch (vSwitch), an error message similar to the following is displayed: "Error applying Virtual Switch Properties changes: Failed while adding virtual Ethernet switch connections."

The error happens because a Broadcom driver that is installed after running Microsoft Windows Update is not certified by Oracle.

Workaround

Broadcom driver version 20.8.24.0 is certified by Oracle. Install version 20.8.24.0.

Details

When you run containers on a Compute instance that uses Ubuntu 20.04, kernel version linux-oracle-5.13 5.13.0-1033.39~20.04.1, a kernel panic occurs. The instance crashes and is inaccessible. For more information, see Docker container creation causes kernel oops on linux-aws 5.13.0.1028.31~20.04.22.

Workaround

Upgrade the kernel to a higher version by running the following commands:

Copy

sudo apt-get update

Copy

sudo apt-get upgrade -y linux-image-oracle

Details

E3/E4 flex shape VM instances created before April 5, 2021 fail to start if the memory is resized to more than 1,010 GB. In this case, you see an error that reads "failed to start."

Workaround 1

Reduce the size of memory to less than 1,010 GB.

Workaround 2

Create the instance again, and then resize the instance memory up to 1,024 GB.

Details

Oracle Autonomous Linux is not supported for Always Free compute instances, but in the Console, Oracle Autonomous Linux appears in the list of supported images for Always Free shapes.

Workaround

We're working on a resolution.

Details

In the US East (Ashburn) region, when Oracle Linux instances first boot after provisioning, DNS might not work as expected, and the search field in the /etc/resolv.conf file might be incomplete.

Workaround

Either reboot the instance or wait for the next DHCP lease renewal. After the DHCP lease renewal, the issue resolves automatically. The standard DHCP lease time is 24 hours but varies depending on network settings.

Details

When you create a shielded instance using Linux 7.x and then reboot the instance, PCR values might change, causing the red shield to appear.

Workaround

Some PCR values change at runtime. That change is expected. As a workaround, reset the golden measurements.

Details

Bare metal instances that use the BM.Standard.A1.160 shape experience reduced network performance for workloads running on socket 1 CPUs.

Workaround

For applications responsible for processing packets from the network, bind them to CPUs from socket 0.

Details

When you provision a compute instance on Windows in a private subnet with a service gateway attached, the Oracle Cloud Agent plugins might not emit metrics.

Workaround

Follow the steps in the Microsoft known issue article: Connectivity issues if the DigiCert Global Root G2 root certificate is not installed.

Details

Instances that use the VM.Standard.A1.Flex shape with hardware-assisted (SR-IOV) networking might face performance issues, and in rare cases, data corruption. To prevent this, platform images for OCI Ampere A1 Compute (aarch64) are configured to use paravirtualized networking only. If you create an instance using a platform image and specify hardware-assisted networking, the launch will fail with a message similar to Failed to validate instance launch options.

For custom images compatible with OCI Ampere A1 Compute, the launch will succeed, but we strongly recommend not selecting hardware-assisted networking to avoid potential performance and data corruption issues.

Workaround

When you create a VM.Standard.A1.Flex instance using a platform image, let Oracle choose the recommended networking launch type. For custom images, do not use hardware-assisted (SR-IOV) networking.

Details

Instances that use the VM.Standard.A1.Flex shape with hardware-assisted (SR-IOV) networking and have a large number of cores have improved performance over using paravirtualized networking. SR-IOV networking, however, limits the number of cores to 76 and the amount of memory to 456 GB.

If you try to create an instance that exceeds either of those limits, then an error occurs stating that there is insufficient capacity to create the instance.

Workaround

We're working on a resolution.

Details

When you use Terraform to create an Intel or AMD compute instance using a Linux platform image, the operation might fail with the error code InvalidParameter and a message similar to Shape <shape_name> is not valid for image <image_OCID>.

This happens if Terraform identifies the latest image based on the image display_name. Images for Intel and AMD shapes (x86 processor architecture) have similar names to the images for Arm-based shapes (aarch64 processor architecture), but the images are not cross-compatible across processor architectures. If the latest image is an aarch64 image, Terraform selects an aarch64 image for an x86 shape, causing the operation to fail.

Workaround

Modify the following Terraform files:

• /home/opc/JDERefArch_InfraProvisioning/TerraformScripts/global/global.datasources.tf
• /home/opc/JDERefArch_InfraProvisioning/TerraformScripts/pd/pd.datasources.tf
• /home/opc/JDERefArch_InfraProvisioning/TerraformScripts/nonpd/nonpd.datasources.tf
• /home/opc/JDERefArch_InfraProvisioning/TerraformScripts/globalDR/globalDR.datasources.tf
• /home/opc/JDERefArch_InfraProvisioning/TerraformScripts/pdDR/pdDR.datasources.tf

In the files, update the regular expression that identifies the image to filter out all images for Arm-based shapes. Images for Arm-based shapes include "aarch" in the image name.

For example, for Oracle Linux 8 images, make the following update:

• Current regular expression: values = ["^.*Oracle-Linux-8[.]*[\\d]*-[^G].*$"]
• Updated regular expression: values = ["^.*Oracle-Linux-8[.][0-9]*-[\\d]{4}.[\\d]{2}.[\\d]{2}-[\\d]*$"]

Details

Instances that use the Oracle Linux Cloud Developer image cannot be managed by the OS Management service.

Workaround

Do not install the OS Management Service Agent (osms-agent) on Oracle Linux Cloud Developer instances.

Details

When you try to import or export a custom image from an Object Storage bucket, an error similar to the following might occur:

Invalid bucketName: Specified namespace or bucket to export image does not exist

This error happens for federated users and for users authenticating with instance principals tied to a dynamic group.

Workaround

Create a pre-authenticated request, and then use the pre-authenticated request to import or export the image. Pre-authenticated requests provide a way to let users access a bucket or an object without having their own credentials. For detailed steps explaining how to create and use pre-authenticated requests, see Using Pre-Authenticated Requests and Pre-Authenticated Requests.

Details

When you try to create an instance from a boot volume backup in the Console, an error similar to the following might occur:

"There was an error loading the source image for creating an instance. You might not have permission to access this image, or it might be in a different region. If the image is in a different region, you should still be able to launch your instance."

This error can occur when the compartment that contained the deleted image metadata used for the boot volume backup has also been deleted.

Workaround

If the compartment has been deleted, use the CLI to create the instance. For information about using the CLI, see Command Line Interface (CLI).

To create an instance from a boot volume using the CLI, open a command prompt and run the launch command. To launch an instance using an image or a boot volume, include the --source-details parameter.

Command

CopyTry It

oci compute instance launch --availability-domain <availability_domain> --compartment-id, -c <compartment_ocid> --shape <shape> --subnet-id <subnet_id> --source-details <file://path/to/file>

Details

It is not possible to remove an instance from a capacity reservation using Terraform.

Workarounds

Use either of the following workarounds:

• Use the Console, CLI, or SDK to remove the instance from the capacity reservation.
• Using Terraform, to enable you to remove an instance, set the capacity_reservation_id to a space, as in the following Terraform script example:

  capacity_reservation_id = " "

Details

When you create more than 50 capacity configurations in a capacity reservation, an internal error occurs. After the error occurs, it's not possible to launch instances against the capacity reservation.

Workaround

To avoid this issue, do not add more than 50 capacity configurations to your capacity reservation.

Details

The <shape>-core-reserved-count service limit numbers are inaccurate. The number in the Service Limit column might show 1,000,000,000 or N/A. The number in the Available column might show 1,000,000,000 less the number in the Usage column or N/A. The 1,000,000,000 value represents a maximum value and might vary.

Workaround

For accurate service limits, see Compute Capacity Reservations.

Details

When you request a service limit increase, the Service Category menu does not include a category for capacity reservations.

Workaround

In the Request Service Limit Updates form:

• For Service Category, select Others.
• For Resource, select Other Limits.
• In the Reason for Request field, enter the specific limit to be increased.

Details

When you try to create an instance pool, the instance pool creation fails with the error "Authorization failed or requested resource not found". This happens because resources used by the instance pool contain default tags, and the user does not have permission to the tag namespace.

Workaround

Add a policy statement granting the instance pool user group permission to the tag namespace Oracle-Tags:

Allow group InstancePoolUsers to use tag-namespaces in tenancy where target.tag-namespace.name = 'oracle-tags'

For more information about policies, see Let users manage Compute instance configurations, instance pools, and cluster networks. For more information about default tags, see Understanding Automatic Tag Defaults.

Details

When you try to create an instance, the instance launch fails with the error code InternalError and a message similar to Out of host capacity. This happens because of a lack of physical infrastructure capacity for the shape in the requested fault domain and availability domain.

Workaround

Capacity usually becomes available soon for most shapes. To work around this issue, do the following things:

• To determine whether capacity is available for a specific shape before you create an instance, use the CreateComputeCapacityReport operation.
• If you're using a previous generation shape, create the instance using a current generation shape instead. Capacity is limited for previous generation shapes.
• Create the instance in a different availability domain.
• Create the instance without specifying a fault domain.
• Create the instance using a smaller shape, or using a shape in a different series.
• Wait a few minutes and try again.

Details

When the in-transit encryption value for an image is null, the in-transit encryption value for an instance that's created from the image can be set to a non-null value.

Workaround

We're working on a resolution.

Details

When you use a Windows Server instance as a domain controller, features that depend on Oracle Cloud Agent, such as the Monitoring service and the OS Management service, are not available. This happens because the services installed by Oracle Cloud Agent on Windows run with virtual accounts, but virtual accounts are not supported in the domain controller scope.

Workaround

1. Disable the Oracle Cloud Agent updater by running the following PowerShell command as an administrator:

   Copy

   net stop OCAU

   Note
   
   Disabling the Oracle Cloud Agent updater prevents the instance from receiving automatic Oracle Cloud Agent updates in the future. You can update Oracle Cloud Agent manually, but you must repeat this workaround after updating.

2. For each Oracle Cloud Agent feature that you want to use, update the service's running user for the applicable NT service to use a domain user account.

   Ensure the domain account is a member of Performance Monitor Users or Administrators Group according to the following table. Use Active Directory Users and Computers to find an appropriate user account from your domain and ensure the user is a member of the target domain local group, as shown in the following table.

   Oracle Cloud Agent Feature	Target Account Type	Target Domain Local Group
   Oracle Cloud Agent NT service (including the Compute Instance Monitoring plugin)	Domain service account or user account	Performance Monitor Users
   Compute Instance Run Command plugin	Domain service account or a domain user account that has local administrative privileges	Administrators Group
   Oracle Cloud Unified Monitoring Installer Service (Custom Logs Monitoring plugin)	Domain service account or a domain user account that has local administrative privileges	Administrators Group
   OS Management Service Agent plugin	Domain service account or a domain user account that has local administrative privileges	Administrators Group
   Oracle Cloud Agent updater	Domain service account or a domain user account that has local administrative privileges	Administrators Group

3. Use services.msc to update the service's running user to the domain user account with appropriate domain groups.

Details

Due to a change in how the Compute service handles images, when you create a boot volume backup, the backup is larger than expected. In some cases the boot volume backup might be larger than the boot volume size.

Workaround

We're working on a resolution.

Details

You might experience intermittent errors with any of the following tasks for your compute instance:

• Connecting to the instance using SSH.
• Performing a DNS lookup
• Accessing the metadata service at http://169.254.169.254/*.

Workaround

To temporarily work around this issue, run the following command on the instance:

sudo ethtool -G ens3 tx 513 && sudo ethtool -G ens3 tx 512

Details

If you performed a yum update on your instance using the Oracle Linux 7 yum repos between March 22, 2019 and April 9, 2019, you might encounter an issue where iSCSI-attached block volumes are not available after you reboot the instance.

Workaround

This issue occurs when the instance is not configured to automatically login to iSCSI nodes on reboot. To configure automatic login, update the version of the iscsi-initiator-utils package by running the following command:

Copy

sudo yum update -y iscsi-initiator-utils-6.2.0.874-10.0.7.el7

Details

Oracle Cloud Infrastructure supports iSCSI attached remote boot and block volumes to compute instances. These iSCSI attached volumes are managed by the iscsid service. In scenarios where this service is stopped for any reason, such as the service crashes or a system administrator inadvertently stops the service, it's important that the iscsid service is automatically restarted to increase the stability of your infrastructure.

Workaround

For steps to configure the iscsid service to restart automatically, see Updating the Linux iSCSI Service to Restart Automatically.

Details

When you specify a value for the ipxeScript attribute of the Instance for a virtual machine (VM) instance, the instance launches with an iSCSI attachment for the boot volume instead of a paravirtualized attachment.

Workaround

We're working on a resolution.

Details

A compute instance might experience a system hang after you run the following command to reload the firewall:

firewall-cmd --reload

Reloading the firewall using this command on a running instance might cause the instance's boot volume to lose its iSCSI connection and crash, based on the order in which firewall rules are reloaded.

Workaround

To prevent this from happening, do not use the reload parameter for firewall-cmd. Instead, run the firewall-cmd command twice, using the permanent parameter the first time you call it to ensure you do not lose iSCSI connectivity.

For example:

firewall-cmd --permanent
firewall-cmd

Details

On instances running Windows 2016, a red "x" is displayed on the network connection icon in the taskbar even though there is no issue with the instance's network connectivity.

Workaround

If you recycle the explorer.exe process the icon will display the correct status. However, this is not a permanent fix; the red "x" will reappear when you reboot the instance.

Details

iSCSId is disabled by default in the October 2018 release of the Ubuntu 18.04 platform image, so instances using this operating system might experience a system hang if there is a momentary break in the iSCSI communication.

Workaround

Run the following command to enable iSCSId on the instance:

sudo systemctl enable iscsid && sudo systemctl start iscsid

Details

When calling the GetInstance operation or the ListInstances operation, the kmsKeyId attribute of InstanceSourceViaImageDetails is null.

Workaround

Call the GetBootVolume operation and retrieve the value from the kmsKeyId attribute of BootVolume.

Details

After you enable UFW on a compute instance running Ubuntu, the instance fails to reboot successfully.

Workaround

Do not use UFW to edit firewall rules. Platform images are preconfigured with firewall rules to enable instances to make outgoing connections to the instance's boot and block volumes. For more information, see Essential Firewall Rules. UFW may remove these rules so that during a reboot the instance is not able to connect to the boot and block volumes.

To modify or add new firewall rules, update the /etc/iptables/rules.v4 file instead. Modifications to firewall rules here will take effect after a reboot. To have the rules take effect immediately, run the following:

$ sudo su -
# iptables-restore < /etc/iptables/rules.v4

Details

You are unable to log in to an instance launched from a newly created custom Windows image. This issue is the result of the image generalization process failing due to a problem with Sysprep after upgrading to WMF 5.0.

Workaround

Perform the steps described in Sysprep fails after WMF 5.0 installation.

Details

When importing Ubuntu 16 LTS and newer releases of Ubuntu, DHCP fails to get the gateway configuration, and thus fails to set up a default route to the gateway on the VNIC.

Workaround

Statically configure the default route after import. To do this:

1. Create the following script:

   #! /bin/bash -e
   								ROUTER_IP=$(/usr/bin/curl --silent http://169.254.169.254/opc/v1/vnics/ | grep "virtualRouterIp" | grep -oP "\d+\.\d+\.\d+\.\d+" | head -n 1)
   								echo "Found Router IP $ROUTER_IP"
   
   							ip route add default via $ROUTER_IP

   and save it to: /usr/local/bin/configure_default_route.sh

2. Run the following command to make the script executable:

   sudo chmod +x /usr/local/bin/configure_default_route.sh

3. Add the following to /etc/network/interfaces so that it is launched each time the system boots up:

   # OCI Emulated boot network interface
   								auto ens3
   								iface ens3 inet dhcp
   							post-up /usr/local/bin/configure_default_route.sh

Details

When you detach a secondary VNIC from instances launched from imported custom images, the operation might time out.

Workaround

The hot plug module, acpiphp, needs to be loaded for secondary VNICs to detach correctly in Linux. If a VNIC fails to detach, run the lsmod command to display the list of loaded modules, and check the list for acpiphp. If you don't see it in the list, load the module by running the following command:

Copy

modprobe acpiphp

Retry the detachment operation for the secondary VNIC. You might need to reboot the system for the operation to complete successfully.

Details

The secondary VNIC feature is not supported for the following operating systems due to a bug in the kernel:

• CentOS 4, 5
• Oracle Linux 4, 5
• RHEL 4, 5

Secondary VNICs will fail to work after a reboot.

Workaround

We're working on a resolution.

Details

When you try to export an image, the export fails with an error indicating that the image is invalid. This error only occurs in the US West (Phoenix) region.

Workaround

To work around this issue:

1. Launch a new instance based on the image you're trying to export, and specify one of the following shapes for the image:

   • BM.Standard1.36

   • BM.DenseIO1.36

   • VM.DenseIO1.4

   • VM.DenseIO1.8

   • VM.DenseIO1.16

2. Create a custom image using the steps described in Creating Custom Images.

After you have created the custom image, you can export this new image.

Details

When establishing an SSH connection to a bare metal instance, your SSH client must send the correct key the first time. If you have more than one SSH key configured under ~/.ssh or in your ~/.ssh/config file, your client may not send the correct key on the first authorization attempt, and you might encounter the following error message:

Received disconnect from UNKNOWN port 65535:2: Too many authentication failures.

Workaround

Modify the connection string in the SSH command to use the configfile flag -F to override the default configuration file, the -o IdentitiesOnly=yes option to force the SSH client to use the specified key, and the identity file flag -i to specify the SSH key to use, as shown in the following example:

ssh -F /dev/null -o IdentitiesOnly=yes -i /<path>/<ssh_key> -o ProxyCommand='ssh -i /<path>/<ssh_key> -W %h:%p -p 443...

Details

VM instances: You can only create serial console connections to virtual machine (VM) instances launched on August 26, 2017 or later.

Bare metal instances: You can only create serial console connections to bare metal instances launched on October 21, 2017 or later.

Workaround

If you need serial console access to an instance launched prior to the dates specified for VM and bare metal instances, you can work around this issue by creating a custom image of the instance. When you launch a new instance based on the custom image, the new instance will have serial console access. For information about creating a custom image, see Managing Custom Images.

Details

The ListImages API operation includes parameters for server-side filtering on operatingSystem and operatingSystemVersion. However, these parameters are currently inactive. Also, the Image response object documentation includes the operatingSystem and operatingSystemVersion attributes, but the object currently does not return these fields.

Workaround

Refer to the display name for platform images. The display name for platform images includes the operating system and operating system version. For example, with the platform image "Oracle-Linux-7.2-2016.09.18-0", "Oracle Linux" is the operating system and the version is "7.2".

We are aware of the omission and plan to support these parameters and attributes.

Details

If the Network Manager service is installed, an instance can fail to reboot.

Workaround

If the Network Manager service is not required, you can uninstall it. If the Network Manager service is required, modify the network interface configuration file before you reboot the instance. Set the NM_CONTROLLED configuration key to "no":

NM_CONTROLLED="no"

Usually, the network interface configuration file is located in:

/etc/sysconfig/network-scripts/ifcfg-<interface_name>

Details

Some FastConnect networking setups prevent automatic patch updates for utilities such as Oracle Ksplice.

Workaround

In the /etc/uptrack/uptrack.conf file, replace all instances of:

oraclecloud-updates-ksplice.oracle.com

with:

updates.ksplice.<region>.oci.oraclecloud.com 

For example, if your home region is the US West (Phoenix), replace:

oraclecloud-updates-ksplice.oracle.com

with:

updates.ksplice.us-phoenix-1.oci.oracle.com

This workaround applies to service gateways. It does not apply to private endpoints.

Details

When using the OS Management service on Oracle Linux instances that were created before September 2019, the Instance Details page might incorrectly indicate that the OS Management service is enabled (Oracle Cloud Management Agent: Enabled) when the service is not enabled.

This issue affects instances that were created before the isManagementDisabled flag was defined in the metadata for compute instances. Because this flag is not present, the metadata for these instances is not set properly for the OS Management service.

Workaround

To resolve this issue, set the isManagementDisabled flag to false:

1. In the agent configuration for the instance, set the isManagementDisabled option to false:

   Copy

   oci compute instance update --instance-id <instance_OCID> --agent-config '{"isManagementDisabled": false, "isMonitoringDisabled": false}'

2. Use the CLI to verify that the flag has been updated:

   Copy

   oci compute instance get --instance-id <instance_OCID>

   In the output, the updated flag appears as "is-management-disabled": false.

   {
     "data":
       "agent-config": {
         "is-management-disabled": false,
         "is-monitoring-disabled": false
       },
   ...
   }

3. Connect to the instance using SSH, and then use cURL to call the instance metadata service and verify that the flag has been updated within the compute instance:

   Copy

   curl http://169.254.169.254/opc/v1/instance/

   In the output, the updated flag appears as "managementDisabled" : false.

   {
     ...
     "agentConfig" : {
       "monitoringDisabled" : false,
       "managementDisabled" : false
     }
   }

The are currently no resolved known issues in Compute.
