I see 2 ways :
- snapshot with vmstate. (so pending write in memory are saved).
Does this work with rbd snap?
- 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)
Patches? this sounds experimental - patches for guest kernel? For qemu?
