Deploying Oracle Linux 10 VMs from Content Library leaves the VM with no OS setting in vSphere 8.x

Products

• VMware vCenter Server

Issue/Introduction

• While creating a virtual machine, there is no option to select Oracle Linux 10 as the guest operating system.
• To install an Oracle Linux 10 as the guest operating system on vSphere 8.x, select Oracle Linux 9 (64-bit) as the Guest OS in the VM creation wizard. 
• A VM created and configured with Oracle Linux 9 (64-bit) can be cloned successfully from the inventory into another VM even though the running operating system is Oracle Linux 10.
• When the same VM is cloned as an OVF into a Content Library and then deployed as a New VM from this Template, the deployed VM displays:
  • Guest OS Family → Other
  • Guest OS Version → Blank in VM options.
• In the /var/log/vmware/content-library/cls.log, the following warning appears:

Validate target warnings = [OvfWarning (com.vmware.vcenter.ovf.ovf_warning) => { category = VALIDATION, issues = [ParseIssue (com.vmware.vcenter.ovf.parse_issue) => { category = VALIDATION_ERROR, message = Operating system oracleLinux10_64Guest is not supported on any of the hosts, falling back to otherGuest., args = [oracleLinux10_64Guest, otherGuest]

• When exporting/deploying the OVF, the following is seen in ovf descriptor file:

<OperatingSystemSection ovf:id="109" ovf:version="10" vmw:osType="oracleLinux10_64Guest">

<Description>Oracle Linux 9 (64-bit)</Description>

</OperatingSystemSection>

Environment

• vCenter Server 8.0 U3

Cause

• Oracle Linux 10 (oracleLinux10_64Guest) is not supported in vSphere Content Library on vCenter 8.x.
• During deployment from the library, the system defaults to otherGuest, causing the Guest OS field to appear blank.

Resolution

To work around this limitation and ensure a valid guestId is populated:

1. Log in to the impacted Oracle Linux 10 VM console.
2. Create or edit the VMware Tools configuration file:
   vi /etc/vmware-tools/tools.conf


    
3. Add the following content:
   [guestosinfo]

   short-name=oracleLinux9-64
   
   
4. Save the file.
5. Restart VMware Tools service:
   systemctl restart vmtoolsd


6. Wait for the Virtual Machine summary page to update( it may take a few minutes).
   • The Guest OS should now show as Oracle Linux 9 (64-bit).
7. Clone the VM as an OVF into the Content Library and deploy a new VM from the template.
   
   

The change can be validated by exporting the OVF descriptor file.
After workaround:

<OperatingSystemSection ovf:id="109" ovf:version="9" vmw:osType="oracleLinux9_64Guest">

<Description>Oracle Linux 9 (64-bit)</Description>

</OperatingSystemSection>

 

Additional Information

• Oracle Linux 10 support in ESXi
  
  • This limitation affects virtual machines configured with virtual hardware versions 20 and 21.
  • Support for Oracle Linux 10 is introduced with virtual hardware version 22, available in ESXi 9.0.
• For details on hardware versions and supported operating systems, refer to:
