Hi Domien,
Possible it is, but you will need to test this deployment.
The firmware json files are stored under /usr/share/qemu/firmware on each KVM

As far as I understand (I'm not a Veeam expert), if you are taking backup by

Hi,
Non-responsive mean that the Engine application is not able to connect to the
VDSM service running on the KVM host.
Did you check the Engine and KVM host logs?
Many factors may cause this error:
- all kvm hosts have the same kernel version
- kernel modules loaded (kvm)
- network issue
- vds
Did you checked if any log is available regarding that failing test?
On the engine server check:
