Backup failing "No - EFI Disk without OVMF BIOS"

[guff666]

I have a daily backup job running across two nodes with 5 VMs - a mix of LCX and QEMU. One VM is failing, a QEMU running Windows 10.

The job fails on the efidisk (it usaes efi because I'm passing through PCI cards)


Any ideas?

can you post the config of the vm with qm config ID

you have configured an efidisk, but your 'bios' is not set and the default is 'seabios' if you want to use efi you must configure that to 'ovmf'

note that it's not that simple for an os to change from bios to uefi, so you guest may not handle that easily
if you want to keep using seabios, you could simply remove the efidisk

Thanks for that, @dcsapak. You're right of course. At some point the bios changed - no idea when.
