One thing you've missed though is that deletion of snapshots now becomes quite a challenge.
Yeah I did not consider implementing deleting at that moment. However to make external snapshots usable it should be implemented as well.
Yeah, both need to be implemented at the same time.
Anyway is anybody in Red Hat working on this (considering you and Pavel discussed the topic recently)? If not I would like to proceed with implementation.
We definitely plan to work on it, but I can't give you any time estimates yet.
More importantly, since you are interested into this as well, it would be great if you could elaborate on how you want to use this if it's ready especially any special scenarios.
For us the basic goal is to achieve feature parity between internal and external snapshots so that they can be used interchangably and eventually prefering external snapshots as the way forward.
Basically this is what we want to do too. On top of that we want to support asynchronous snapshot/revert to snapshot based on work in progress in QEMU being done by Virtuozzo [1]. We have no any patches for libvirt yet.
Do you mind if we proceed with implementation? I guess I can start more or less right now.

Hi Nikolay, I was assigned to work on this feature as Peter mentioned. I was getting familiar with the snapshot code and I'm starting working on this feature. Pavel
