I already verified (on a 4.1 infra) that changing vm_backup.py downloaded
yesterday from master this way (apart connection paramters):

$ diff vm_backup.py vm_backup.py.orig
 150d149
<         persist_memorystate=False,

I get the backup result and snapshot is correctly without memory saved (and
no pause at VM side)

In engine events I get:

I have almost no experience in gerrit/github, unfortunately... only a
beginner experience in svn ... ;-)
If you give me some pointers I can try to apply what you asked...
