Very good point Gialuca, you are right, the 'persist_memorystate' flag
is 'true' by default, and that makes the pause longer. Would you be so
kind to add it to the 'vm_backup.py' example that is part of version 4
of the SDK?

https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py#L143-L151

(Note that that Gibhub is just a mirror, the change needs to be submited
using gerrit.ovirt.org).

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...
