Allow fallback to userspace only upon migration, only for specific features
and only if 'vhostforce' is not requested.
Changes from v1:
Patch 1 dropeed (will be submitted in another series)
Added device callback in case the migration should fail due to missing features
Hi Yuri:
Have a quick glance at the series. A questions is why we need to do the
fallback only during load?
I think we should do it in the device initializating. E.g when the vhost
features can not satisfy, we should disable vhost since there.
Thanks
