There is no clear use-case for hv-all other than development at this
moment; as Daniel previously stated we may never support it in
libvirt. I decided to take the easiest path first and think about
migration later, when we understand why we would want to migrate such
guests.

In theory, yes, we may compare Hyper-V feature words on source and
destination and allow migration when the former is a subset of the
later.
