Hello everyone,
We run a large number of virtual desktops on RHEV and we use the snapshot mechanism
occasionally. Would it be possible to create automatic snapshots when VM’s are started
and when they are stopped?
My gut feeling says this would be a bad idea, because taking snapshots does not guarantee
anything, but I have the task of exploring the option.
If needed, I would change source code to create something and contribute it.
Currently I have taken a look at
- the vdsm hook mechanism, but that seems to be aimed at the VM lifecycle, not operations
like starting and stopping an instance.
- the ovirt-agent hooks , but they also seem to be useful when migrating a VM
The goal of the snapshot is to have a backup-backup, just handy when dealing with
malfunctions inside a VM workstation, it does not have to be perfect.
Maybe I can create scripts to enable functionality in a different (existing) place, but I
am a bit reluctant to create unnecessary scripting because that creates admin overhead.
Maybe from an architectural point of view automatic snapshots is just a plain wrong idea,
not sure.
What are your thoughts about this?
With kind regards,
Joost Evertse
