Re: Cannot take snapshot ok KVM in 4.8
When would this feature be finally added to ACS? I've been waiting for it for ages. I am sure others using KVM are also looking for a proper snapshotting function in ACS and not what it is at the moment.
Thanks
Andrei

Re: Cannot take snapshot ok KVM in 4.8
Posted by Simon Weller <sw...@ena.com>.
The volume snapshot location depends on the underlying storage. Ceph primary storage is an example where the Ceph snapshot feature is utilized, keeping snaps on primary storage.
I believe Solidfire may also offer a similar functionality, but probably best to us them directly on that front.
The new VM based snapshot on KVM requires QCOW2 images due to the memory snapshot requirement (hence NFS), but it does keep them on primary storage.

Great to hear we are finally getting to the bottom of one of the most annoying things still present in ACS when it comes to KVM hypervisors! I can't wait to try it out ))). The last remaining thing to do is to have the ability to keep the volume snapshots on the primary storage and use the storage's snapshotting capabilities. I think there is work in progress here as well )))

It was rebased for 4.9.
We have it build currently in one of our labs as of yesterday. It seems to be functioning as it should, although we're going to be putting it through it's paces over the next few days.
