[ovirt-users] restore snapshot cannot restore memory
hello
I found if we retore snapshot, memory cannot be restored, I test it with
ovirt-4.1.2、vdsm-4.17.0 and libvirt-3.0.0,
and i get some errors in [1],it seems vm not paused in creating snapshot, but
self._underlyingCont() called in vm starting,
so error occurs, then vm is started in libvirt but shutdowned in vdsm, changes
in [2], then it works well.
