Hi Leszek,
using Ceph and qcow2 is not something we have leveraged. Maybe someone from
the community can report their experiences?
I've created a feature report to see if we can add support for this.

I can't migrate to NFS because the disk io performance won't handle my VM's.
There isn't any sunstone modification to use rbd v2 images snapshots ? I
can create them using rbd snap create, but don't have the possibility to
use it via sunstone.

You need NFS datastore. Only NFS or SSH datastore support qcow2 file
format. But Opennebula can't move ima
I've forgot to tell that i've upgraded my opennebula to 4.6 version.

Can you write me what i need to do to migrate to qcow2 format? I've got
running vm's that cannot be "deleted". I tried migrating them form rbd v1
to v2 but this doesn't solved my problem.

I'm not sure I follow you with that. Just changing the TM from ceph to
qcow2 is something that probably doesn't work. One of the things that
can be failing is that getting the free space from ceph and qcow2 is
totally different and it may be that the datastore is reporting 0
bytes free. In this cas
I tried to change rbd image version from 1 to 2 but it doesn't work. But
when i changed in my ceph datastore TM_MAD to qcow2 the new VM instantized
from image that was in the datastore stuck on "PENDING". Is there any way
to get this working with "existing" images?

I did some experimental work on this with our OpenNebula 4.4 instance.
It relies on modern kernel'
System snapshot is only supported in KVM for qcow2 disks [1] so it
won't work with your ceph datastore. If you want to use system
snapshots and copy on write use the qcow2 datastore [2].

1) I'm using OpenNebula 4.4 with ceph datastore. When i try to make
snapshot i've got error:
error: unsupported configuration: internal checkpoints require at least one
disk to be selected for snapshot
I'm using qcow2 images converted by opennebula to raw when uploaded. Can
anyone help me ?
