Is normal behavior a outage when a snapshot occurs? Ive got the rhev builds installed but when I take a snap im getting well over two minutes of downtime, on a VM with zero usage. The VM goes into "pause" state then, I guess the snapshot is a copy of the entire VM? I have not got a second host up with those rhev build to see the behavior when disk migrating Thanks On Sat, Jul 5, 2014 at 7:51 AM, Brad Bendy <brad.bendy@gmail.com> wrote:

Haha, yeah never have been a Fedora fan, and nothing has changed. Is the only big feature im missing out on is snapshots? From what I can tell, and in my testing, everything else seems to work. Was deploying GlusterFS but without the live migration to another host that is somewhat defeated.
VM live migration works, live _disk_ migration does not.
Only way to get that is with RHEL really then?
No, as I earlier pointed out, there is a place you can get the packages you need for CentOS: http://jenkins.ovirt.org/view/All/job/qemu-kvm-rhev_create-rpms_el6/lastStab...
You'll have to download- and force install them over the already installed versions of those packages on all Hosts and then it'll work.
Though, next time there are updates, yum will update from the standard repos and it just stops working again until you repeat the procedure.

If I use Fedora will "everything" work? I had numerous issues, IIRC I could not even get the ovirtmgmt switch to install and a few other things. What version of Fedora do you recommend then?
None:) We switched long ago to CentOS and have never looked back, even with these issues. Not worth the headache that is Fedora.
/K
Ill do another install and give that a whirl again.
Thanks!

Well, going with Fedora would at least get you the snapshots working, if I remember correctly, but that's not something you run in production. As you said, "major issues".
For CentOS, you need "special" versions of certain packages, since RedHat wants you to pay for RHEV, they have chosen to cripple the standard packages so those features won't work: http://lists.ovirt.org/pipermail/devel/2014-June/007735.html
And here you can find the packages you need:
