Not sure if that can be done. KVM virt on aarch64 and x86 can support EFI via AVMF / OVMF firmware built from the edk2 project from a technical POV. The first challenge will be that many mgmt tools still default to using legacy BIOS when deploying guest OS. We've been trying to make it easier for mgmt apps to "do the right thing" by having libosinfo record metadata about whether each guest OS supports legacy BIOS, EFI or both. ie we want the mgmt apps to just pick EFI if they see the OS doesn't support legacy BIOS, instead of requiring users to manually tell them to use EFI. Historically we've tended to discourage use of EFI on virt because, unless you wanted SecureBoot for your VMs, it hasn't offered much in the way of compelling benefits to users. The EDK2 project code is a much higher maint burden for virt than the seabios was, and there's no sign that situation will improve. So I can't say I'm thrilled about a future that depends on EFI for virt, but I'm resigned to the fact this is the direction the world is taking. So we're not likely to have any choice and will have to work to mitigate any downsides it brings.
