[pve-devel] consistent backups / snapshots

[Alexandre DERUMIER]

I see 2 ways : 

- snapshot with vmstate. (so pending write in memory are saved).
- implement qemu guest agent qmp protocol ,and send fs-freeze qmp command to freeze the filesystem, before doing the snapshot.
  (I have seny some prelimary patches some months ago, need to be polish)

Hello list, 

i was trying to make consistent rbd snapshots. What is the recommanded 
method in PVE / qemu to flush all buffers / be able to make a consistent 
backup?
