Bug Description

Not sure if this is related to bug 1452016, or just a HW issue:

With the uvt-kvm create command on this Artful system, it returns:
uvt-kvm: error: libvirt: unsupported configuration: ACPI requires UEFI on this architecture

With the same command running on a Xenail system + Artful kernel, it returns:
qemu-system-aarch64: Cirrus VGA not available

Issue can be found on ThunderX as well, there was a similar bug for it (bug 1751718), but it's for Bionic (Bionic works fine)

After changing the guest image to match the host (e.g. bionic on bionic), this seems to be working now.

Tested with B / D, need to keep an eye on this for other releases.

Marking this as invalid, referenced bugs are all closed and pretty sure this is not a problem on arm64 any longer.
