Hi, I just published the result of the testing of oVirt 4.4.7 with Ceph
Pacific and RDO Victoria for deploying an oVirt datacenter using Ceph as
storage with a blog post at
https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacen...
Comments and suggestions are welcome.
Thanks,

- How to change image features?
- How to add upmap option to libvirt domain?
- How libvirt domain looks like?
- How snapshots works?
Snapshot works fine, going to VM tab and creating snapshot as usual.
- How clones works?
Disk copy can be done from the engine storage -> disk tab.
VM cloning failed for me, opened *Bug 1982083*
<https://bugzilla.redhat.com/show_bug.cgi?id=1982083> - Cloning VM with
managed block storage raise a NPE
- How to migrate images from one domain to another?

New subject: [ovirt-users] Re: Blog post - Using Ceph only storage for oVirt datacenter
I'm mean not this. BLL.Storage currently remove 'standard' Ceph integration
for libvirt and use kernel mounts instead this. Again: removed, because in legacy cinder
integration works in qemu process without any mounts.
Any plans to add libvirt librbd variant to oVirt back?
Thanks,

Hi all,
does it mean that it will be possible to use the drbd storage in the ovirt
environment?
Thanks
