VM live migration works, live _disk_ migration does not.

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/lastS...
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.

New subject: Live Migration / Snapshots- CentOS 6.5
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

New subject: Live Migration / Snapshots- CentOS 6.5
While I have never tested or used this feature myself, I'm pretty
sure this is not normal behaviour, this shouldn't take that long
on an idle vm, unless something else puts your hardware under heavy
load?

Thought I was smooth sailing, guess not.
When I did this clone would I need to reset the Sanlock UUIDs? Im
getting a bunch of weird errors when going to activate a gluster
storage domain to the datacenter.
