Very needed functionality IMHO, even currently partially supported for cloning guest-vms using KVM and NetApp:

Thanks in advance.

Thanks Itamar.I heard the other day that NFS v4.2 is supposed to contain server side copy, so it's possible that we might see this kind of support in one of more storage domain available to ovirt at some stage perhaps next year (in Fedora at least).Is this something that Gluster will also likely provide in a subsequent release once we have proper gfapi support?
I'd be interested to hear if others on the list are clamouring for server side offload support in some form.

yes, on the roadmap, tbd yet on when. netapp did a plugin enabling this
for their storage array (VSC plugin)
I hope the ceph integration will provide this, though that doesn't solve
it for other type of storage domains yet.

Back in May (see http://lists.ovirt.org/pipermail/users/2014-May/024004.html
and following answers) we talked about Fedora Server and that Fedora 21
Server would have been a preview of that...
Now that it is out officially, it would be nice to see if oVirt
Hypervisor/Engine could become sort of Server Roles, as stated at
https://getfedora.org/en/server/
"
Server Roles and Rolekit
There's no need to set up your server from scratch when you use server
roles. Server roles plug into your Fedora Server system, providing a
well-integrated service on top of the Fedora Server platform. Deploy and
manage these prepared roles simply using the Rolekit tool.

The zanata source text is generated from default values from the ovirt source
code. Einav should know more about exactly how that is done. You should always
match the translation to the source and not the other way around. So I am not
sure why you are trying to change the source.

I suggest to open a RFE in bugzilla for it, but it won't be in 3.5.z. I'm not even sure if we can make it for 3.6.
BTW I think it's an interesting RFE.

Bugzilla created against ovirt-engine-installer and version 4.0:
https://bugzilla.redhat.com/show_bug.cgi?id=1174236
Do you think it is better to create another one specifically for oVirt
Hypervisor? And in that case against what component?

BTW: I put [RFE] at beginning of subject. I hope it is sufficient to mark
it as an enhancement bugzilla entry...
