Unable to create some VMs

[Dinac29]

Getting a response back from pvedaemon when trying to create some VMs of:

Failed to create VMs: VM creation failed: {'id': '107', 'exitstatus': "unable to create VM 107 - backing file not allowed for untrusted image '<subsequent image info here>}

I haven't been able to find anything close to this on searches. I'm just getting my feet wet with Proxmox and I'm looking to possibly move to it from Ovirt.

Currently running Proxmox VE 8.3.0.

Any pointers would be highly appreceated!

Hi,
that means the image you are importing from references a second file, i.e. the backing file and this is prohibited by Proxmox VE. Use qemu-img info to see what it is. If the backing file is part of your import source and not some unexpected reference to another place on the system, you can create a single data image via qemu-img convert for example and then import from there.

Interesting, thanks for the reply! I'll look into turning these into a single image. Only followup I have to this is that they appear to all be the same but only some are called out. Not sure what's going on there, but if I can get the single data image working, I'll convert them all the same way.

I figured it out, the backing file is from a snapshot of the disk. Deleting the snapshot collapses the disk image.
