Cannot snapshot VM - VFIO migration not supported

[TheBokke]

Hi folks,

I'm trying to snapshot a VM running TrueNAS Scale. Never had any issues before, but when trying to create the snapshot I get this error:

TASK ERROR: VM 100 qmp command 'savevm-start' failed - 0000:01:00.0: VFIO migration is not supported in kernel

I read something about the NoVNC clipboard in this thread:

https://forum.proxmox.com/threads/qmp-command-savevm-start-failed-the-vdagent-chardev-doesnt-yet-support-migration.174785/imilar issue.

But I don't see a solution or workaround.

Any suggestions appreciated.

Hi,
migration with noVNC clipboard will be supported in an upcoming qemu-server release, under the condition that the machine version of the VM is at least 10.1. It's already applied in git, but it's not packaged yet.

Thanks Fiona. Is there another way to create a snapshot not using noVNC clipboard? I don't seem to have this issue on my other VM's and can create a snapshot from the Proxmox UI no problem.

Unfortunately no. You'll have to wait for the new qemu-server package (or apply the patch yourself if you have experience with such things), then snapshots and migration will work for VMs running machine version >=10.1.
