Since you don’t need the PCI device for the backup, you can temporarily disable it in the VM config:
# Edit VM 192 config
nano /etc/pve/qemu-server/192.conf
Comment out the PCI line(s):
#hostpci0: 0000:01:00.0
Then run your backup again...

Make sure there are no spaces or special characters...
Hi,
Changing a VMID directly isn’t supported in Proxmox. The recommended way is to back up the VM and restore it using the new VMID. This ensures everything stays consistent and avoids storage issues,
Hi,
We are looking for a PVE cluster resource load balancing function similar to VMware DRS automation. Does the PVE cluster have a similar function for automated resource load balancing?
Thank you
