My storage is gluster, hosted on the F20 machines. I'm seeing some SELinux issues right now, so I'm in permissive mode until I can file bugs for them.

Re: [ovirt-users] Live Migration / Snapshots- CentOS 6.5
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.

Re: [ovirt-users] 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?

That behavior is expected, engine pauses the VM during snapshot to ensure consistency. Not as sure about the timeframe though; two mins for a idle VM? When I snap, it's a matter if seconds, but that might be your Gluster spooking. We use a traditional NFS server.

Re: [ovirt-users] 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 On Sat, Jul 5, 2014 at 7:51 AM, Brad Bendy wrote: > There we go, sorry about that!

Re: [ovirt-users] Live Migration / Snapshots- CentOS 6.5
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. Only way to get that is with RHEL really then?

Re: [ovirt-users] Live Migration / Snapshots- CentOS 6.5
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? Ill do another install and give that a whirl again. Thanks!

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: http://jenkins.ovirt.org/view/All/job/qemu-kvm-rhev_create-rpms_el6/lastStableBuild/ /K ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] Live Migration / Snapshots- CentOS 6.5
Hi, Ive seeing conflicting info with what version of qemu rpms are needed to do live migration under CentOS. It appears the stock ones will not work and the RHEV ones are required. All the mailing list post I see are from 3-4 months ago, so not sure. Im getting VDSGenericException: VDSErrorException: Failed to SnapshotVDS, error = Snapshot failed, code = 48 (Failed with error SNAPSHOT_FAILED and code 48) I also saw this thread: http://comments.gmane.org/gmane.linux.centos.general/138593 Ive been having issues getting those to install, but before I spent to much more time I wanted to really see if I was on the right track. Is there a better OS choice? I first started trying with Fedora 19 and 20 and has major issues, went to CentOS 6.5 and this is the first and only issue so far ive ran into. Thanks! ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
