Hello,

The problem was actually failure to import an existing VMs from an existing oVirt storage into OLVM if the image is configured to use QXL/Spice. (The import UI doesn't let you change the VM display configuration. It will simply fail to import the VM).
I fixed the problem by attaching the storage to a working CentOS based oVirt cluster, changed the console configuration on all the stored VMs to VGA/VNC and detached the storage.
Once the VMs were configured to use VGA/VNC, OLVM managed to import them without an issue.

In short, anyone contemplating moving to OLVM - make sure all VMs use VGA/VNC.

Thanks everyone for the help.

Hi,

If I understood well, the OS guest doesn't have support for VNC, just QXL/Spice.
So... I guess you need to install the vnc drivers on the guest before the migration, buuut I think this should already be installed...
I believe that the best way to "import" is to use the ovirt-img download-disk and ovirt-img upload-disk cli to download and upload the disk to new domain-storage, so after, to create the new vm configuration.
I passed this issue many times.

Cheers,

Hello,

Thanks for the prompt reply.
Can I somehow modify the VM configuration on disk (v5 data storage on an NFS share) before importing the VM (using Storage domain / NFS / VM import).
Alternatively can I somehow get OLVM to ignore the error when trying to import the VM, and use the UI to switch VGA/VNC?

Hi Gilboa,

 

The spice protocol has been deprecated by Red Hat for over 3 years. It may still be available in CentOS or RHEL versions but not in OL.

It cannot be enabled.

Subject: [External] : [ovirt-users] Importing VMs from CentOS 8 Streams to Oracle 8.9 oVirt (QXL issues)

 

Hello all,

 

I'm evaluating switching our existing oVirt clusters to Oracle Linux 8 oVirt 4.5.

It seems that Oracle has completely disabled QXL/Spice (leaving only VGA and Cirrus) on their oVirt fork (1).

I'm trying to import a VM from an existing oVirt data storage into an Oracle cluster, but I'm getting

'VAR__ACTION__IMPORT,VAR__TYPE__VM,ACTION_TYPE_FAILED_ILLEGAL_VM_DISPLAY_TYPE_IS_NOT_SUPPORTED_BY_OS' error.

Comparing the spice-related packages in Oracle and CentOS based oVirt installation, I see no changes.

 

Two questions:

1. Can I somehow enable QXL support in Oracle oVirt?

2. Assuming I can't, can I somehow editing the VM configuration without mounting in a temporary CentOS based cluster, editing the configuration and reimporting it into Oracle?

 

Thanks,

Gilboa
