It would be nice, if ovirt snapshots were more safe. When a VM has the
ovirt-agent installed, ovirt could tell the agent to run site-speficic
actions. What I have in mind is:
linux vms:
- sync
- echo 3 > /proc/sys/vm/drop_caches
- zerofill empty space (this takes long but saves precious backup space)
databases:
- prepare databases for snapshot (flush,write-lock)
- send snapshot-complete and unlock
