Public bug reported:

What?
-----

Add a workaround config option (that will be disabled by default) that
will disable the version-checking of hypervisors during live-migration.

Why?
----

It  can be useful for operators in certain scenarios when upgrading.
E.g. if you want to relocate all instances off a compute node due to an
emergency hardware issue, and you only have another old compute node
ready at the time.

Note, though: libvirt will do its own internal compatibility checks, and
might still reject live migration if the destination is incompatible.
