Thanks Alex. I use virtio and OVMF so hopefully it should be straightforward. I have a separate physical drive for this VM, so under 'storage' in VMM I gave the full drive rather than a partition. However I immediately ran into this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1644848 The suggested fix is to delete .osxsave from the XML, but there is no such string in the file.
