With modern Libvirt switching to EFI is alot easier than it was in the past. You simply need to change <os> element in the XML to add the attribute firmware="efi". No need to mess around with OVMF paths like in the old days - thanks to metadata files defined by QEMU we can auto-pick the right EFI firmware blob. Still, as mentioned elsewhere in the thread there's downsides to EFI, so I wouldn't encourage blindly changing existing guests to use EFI. If they're happy as they currently are, then leave them alone with SeaBIOS.
