Subject: Re: [ovirt-users] Error creating Disks
valid and important discussion indeed.
important enough I think that this should be raised in a separate thread
allowing others to discuss it (since this is an on-going issue some
people may not be aware of a subject change).
Can you please send a new mail with a relevant headline raising this issue?
Thanks,
Dafna

I imagine that all of the features need to be polished before inclusion into RHEL. I'm trying to get my company to adopt RHEL instead of V-Sphere but that is becoming a little tricky. Minus the cool new features of 3.4.x 3.3.4 was pretty stable IMO.
