NOTE: during the snapshot creation I see in web admin console the
VM in paused state and also not responsive in both console and ssh
session.
After a couple of seconds it comes back and as a confirmation I
see this in its messages:
Mar 8 17:38:57 T-ORACLE73 chronyd[616]: System clock wrong by
19.077230 seconds, adjustment started
Is this expected?
Possibly the default changed at some point in time, so that now it
saves memory and so this implies pause of VM
Saving memory is essential in some apàplications like DB, so you won't
bypass vm pauses for such a stuff
In the mean time I verified changing backup.py this way solves the
problem (the 3.6 api deprecation still in place... ;-):
$ diff backup.py backup.py.orig
123c123
<
vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(),
vm=vm,persist_memorystate=False))
---
>
vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(),
vm=vm))
The snapshot doesn't include memory and no problem at VM OS side now
Tested also getting the parameter from config file
Modifications needed in this case:
1)
$ diff backup.py backup.py.orig
123c123
<
vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(),
vm=vm,persist_memorystate=config.get_persist_memorystate()))
---
>
vm.snapshots.add(params.Snapshot(description=config.get_snapshot_description(),
vm=vm))
2)
$ diff config.py config.py.orig
34d33
< self.__persist_memorystate =
config_parser.getboolean(section, "persist_memorystate")
113,116d111
<
<
< def get_persist_memorystate(self):
< return self.__persist_memorystate
And in config file called add:
# Save Memory in snapshot
persist_memorystate=False
It could be further improved if one wants to differentiate save memory
for some VMs and not for other ones....
HIH other ones,
Gianluca
