I am not familiar with libvirt and I would like to play with this only with
qemu.
With failover, we need to hotplug the VF on destination server to VM after live
migration. However, the VF on destination server would have different mac
address.
How can we specify the mac for the new VF to hotplug via qemu, as VF is only a
vfio pci device?
I am trying to play with this with only qemu (w/o libvirt).
Thank you very much!
