I got the following error when backing up overnight:

Code:
ERROR: Backup of VM 114 failed - PCI device '0000:15:00.0' already in use by VMID '107'

Now I know why this is - just as it says, the PCI device (a GPU in this case), is already in use.

However, I wonder what the recommended solution is? I have various VMs that are all setup to use the same GPU, and often I'll leave one running doing some kind of background job.

I don't therefore want to have to stop the VM that has the GPU currently, just to backup all the others. Is there a way to automate this so the VM being backed up doesn't demand the PCI device is available?
