Gluster VMs Paused State then not resumable
by Andrew Lau
Hi all,
I'm wondering if anyone's had any luck with running VMs on top of a gluster VM?
I have a bug open here,
https://bugzilla.redhat.com/show_bug.cgi?id=1058300 about VMs going
into a paused state and not being able to resume.
It's gone a little quiet, so I was wondering has anyone else had any
luck with this style of setup? I have my gluster and virt on the same
boxes, and currently 5 in the cluster (replica 2)
A few cases this can be reproduced:
- switch dies
- cable unplug
- gluster volume stop
- gluster brick dies
I recently tried a suggested volume option:
gluster volume set vm-data network.ping-timeout 10
The qemu logs now report on virsh resume vmname:
block I/O error in device 'drive-virtio-disk0': Transport endpoint is
not connected (107)
Thanks,
Andrew

Live Snapshot issue (once more) with the new QEMU Packages (V10) from CENTOS Updates
by Christian Rebel
Hi all,
after today's CentOS "yum update", I had once more the Problem with LIVE
Snapshots due to the new "qemu packages".
Can anyone explain me why there is such a huge difference between the
"CENTOS QEMU Packages" and the "Jenkins RHEV qemu Packages".
CENTOS QEMU = LIVE Snapshot failed (tested with qemu versions V8 and V10)
* VDSErrorException: VDSGenericException: VDSErrorException: Failed to
SnapshotVDS, error = Snapshot failed, code = 48
JENKINS QEMU = LIVE Snapshots ok (tested with qemu versions V8 and V10)
* Command CreateAllSnapshotsFromVm, Parameters Type
org.ovirt.engine.core.common.asynctasks.AsyncTaskParameters) returned status
finished, result 'success'.
Thanks!

Network traffic being mirrored
by Jim Rippon
--=_4ab7acf68b2ea1ad39d80d5183539e8e
Content-Transfer-Encoding: 7bit
Content-Type: text/plain
Hi guys,
I am seeing network traffic being sent to all my VMs on one of my oVirt
hosts, but not the other two in that same datacentre. The VMs are
running CentOS, and I've been monitoring the sessions with iptraf, and
can see traffic from all other VMs on that network being received by all
other VMs running on this host which have an interface on that same
network.
Is this something anyone has seen, or could anyone suggest anything I
should be looking at to further diagnose?
Many thanks,
Jim Rippon

What about engine-cleanup? Did you run it?
Also, engine-setup generates a log file (you should find its reference in
output). share it with the list so that one of the developers could help
you....

localdomain
by Koen Vanoppen
Hi Guys,
It's bin a while :-). Luckily :-).
I have a quick question. Is there a way to change the default .localdomain
for the FQDN in ovirt?
I would be handy if we just had to fill in the hostname of our vm (we are
using 3.4, with the cloud-init feature) and he automatically adds our
domain in stead of .localdomain.
Kind regards,
Koen

oVirt - Node install on CentOS
by Simon Barrett
--_000_D86C48DF8800164BBE50B87623F7AC9548391A9Fln2wio001devtra_
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
Could anyone please confirm the correct process to run oVirt node on a stan=
dard CentOS install, rather than using the node iso?
I'm currently doing the following:
- Install CentOS 6.5
- Install qemu-kvm-rhev rpm's to resolve live snapshot issues on t=
he CentOS supplied rpm's
- Yum install vdsm ovirt-node-plugin-vdsm vdsm-reg
o I have to remove noexec from /tmp or the config fails
- I then add the node from the ovirt-engine gui
After resolving some problems with group memberships and vdsm requiring sud=
o access, all is working. Live snapshots and storage migration are OK (test=
ed NFS and Gluster as well).
I couldn't really find any docs on how to do this so I just wanted to confi=
rm if what I am doing makes sense.
I also don't have the text configuration interface that I would normally ge=
t on the oVirt node iso. Can I install this and use it on a non node iso in=
stall?
Many thanks for any assistance.
Simon

novnc error
by Garrett Baltezegar
Hello everyone,
I'm running into an error getting novnc up and running with ovirt, and I'm
hoping someone can help.
My system is a CentOS minimal x86_64 install running ovirt fine. I have
created VMs and I'm able to configure the console options. When I attempt
to connect to them, however, I get a Server disconnected (code: 1006)
error. I've searched online for a solution, but everything seems to point
to simply running the engine-setup configuration utility and installing the
ca.crt. I have tried both of these things, but I keep getting the same
message, in Internet Explorer, Chrome and Firefox.
Disabled iptables and selinux.
Connected directly to VM with VNC
Checked ovirt-websocket-proxy, and it is running - haven't touched config
file - SSL=true
Installed ca.crt - multiple times
Reinstalled ovirt - clean first, the reinstall.
Reinstalled ca.crt
Nothing has helped so far. Does anyone have any ideas? I have a
straight-forward setup using engine-setup; accepting the default answer
most of the time. GlusterFS being one of the non-defaults.
I appreciate your suggestions!

python-sdk: attach disk snapshot to another virtual machine
by Michael Ablassmeier
hi guys,
according to an commit in Oct. 2013 there was a patch added to the SDK
which allows to attach an existing snapshot to a virtual machine:
commit 72e67dd5406f3c193234697ce88d92dbe64759d7
Author: Michael pasternak <mpastern(a)redhat.com>
Date: Wed Oct 30 11:24:19 2013 +0200
sdk: regenerate against the latest api
[..]
- added ability to attach a disk snapshot to the virtual machine
[..]
I think this may be related to the new backup API:
http://www.ovirt.org/Features/Backup-Restore_API_Integration
can anyone give me an pointer on how to this through the python-sdk? Or
is there an example for this anywhere to be found? Thanks!
bye,
- michael
