[Users] Reimporting storage domains after reinstalling ovirt
by Boudewijn Ector
Hi Guys,
Currently I've got a Centos machine running the latest ovirt-release.
This machine is using a local raid set containing a directory with
ovirt-based VMs from my previous install. The ovirt install is a
completely fresh install, no storage/VMs have been created yet.
What's the best way to reimport those? I might try to create a new
storage domain and copy all old VMs into it (if that works anyway...) ,
or just reimport the old domain from the web-interface.
Does either trick have any advantage, or is there a best practice I
should adhere to?
Cheers,
Boudewijn

Hi
Yes I'm using glusterfs as storage domain, and glusterd is running on the
ovirt nodes.

New VM from template, vm disk creation time very high
by Steve Dainard
When I create a new vm from a template (centos 6, 20gig thin disk) it takes
close to 40 minutes to clone the disk image.
Are there any settings that control how much bandwidth the cloning process
can use, or how its prioritized? This is brutally slow, and although a
quick clone isn't needed often, occasionally when someone is asking for a
resource it would be nice to expedite the process.
Storage: Gluster replica 2 volume
Network: 10gig
Ovirt: 3.3.4, Centos 6.5
Thanks,
*Steve*

VDSM Shutdown Scenario
by Neil
Hi guys,
I'm trying to setup the simplest yet safest way of protecting my
guests during an unexpected power outage.
If I'm running ovirt with 3 hosts, and the ovirt-engine machine as
well as the hosts have SNMP UPS monitoring software installed and
configured to shutdown if the UPS starts running out of power, what
would happen to the guests when the hosts commence the shutdown
sequence caused by the UPS software? The ovirt-engine would also be
configured to shutdown during the outage.
Would the guests try to migrate to another host (despite all of the
hosts commencing the shutdown)? Would the guests be paused?
What is the recommended practice to safely protect the VM's ?
Thank you!
Regards.
Neil Wilson.

New host ssh error
by Drew Showers
Hello,
I'm trying to add a 2nd vdsm host in an existing working cluster and host
(host 1). It seems all the service are running (vdsmd, nfs, and network) on
host 2.
When I create the new host, it begins installing packages, but then get the
following error:
"Host Host-2 installation failed. Command returned failure code 1 during
SSH session [user@host]".
I can't seem to find the solution on google. I can ssh into host 2 from the
ovirt engine. I've tried it with iptables on and iptables off.
Any help would be greatly appreciated.
Many thanks,
Drew

Repository ovirt-epel is listed more than once in the configuration
by Jorick Astrego
After upgrading to ovirt-release-11.2.0-1.noarch.rpm through yum, I see
the following message when I use yum update again:
Loaded plugins: fastestmirror, security, versionlock
Repository ovirt-epel is listed more than once in the
configuration
I see two entries referencing ovit-epel in the repos:
/etc/yum.repos.d/ovirt-epel.repo
/etc/yum.repos.d/ovirt-dependencies.repo
Shouldn't one of them get removed during the update?
Kind regards,
