No there isn't anything. Libvirt is locking only on internal events that
need protection.
Doing transaction locking should be relatively easy to implement on
application layer though.
Sure we can implement a lock manager on the API client side, but it
can't lock VM for other clients. And that’s the problem for us.
Are maintainers interested in VM lock manager on the server side?
Can I move in this direction or you have something against it?
