This involved a few fixes. To start with, an virDomainSnapshot object is really tied to a domain, not a connection, so we have to generate a slightly different object so that we can get at self._dom for the object. Next, we had to "dummy" up an override piece of XML with a bogus argument that the function doesn't actually take. That's so that the generator places virDomainRevertToSnapshot underneath the correct class (namely, the virDomain class). Finally, we had to hand-implement the virDomainRevertToSnapshot implementation, ignoring the bogus pointer we are being passed. With all of this in place, I was able to successfully take a snapshot and revert to it using only the Python bindings. Signed-off-by: Chris Lalancette <clalance@redhat.com>
