Unable to create KVM with uvtool on arm64 system (Cirrus VGA not available)

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
