that did not help. VDSM log tells me that the delta qcow2 file is missing:

Indeed, retry live merge. There is no harm in retrying live merge. As menti=
oned, if the image deleted at storage side, retrying live merge should clea=
n the engine side.

Hi,
we are on OVirt 4.0.4. As explained the situation is as follows:
- On Disk we have the base image and the delata qcow2 file
- Qemu runs only on the base image
- The snapshot in Qemu is tagged as illegal
So you say: "Just retry a live merge and everything will cleanup."
Did I get it right?

Hi Markus,
What's the version that you are using?
In oVirt 3.6.6, illegal snapshots could be removed by retrying to live merg=
e them again. Assuming the previous live merge of the snapshot successfully=
completed but the engine failed to get the result, the second live merge s=
hould do the necessary cleanups at the engine side. See https://bugzilla.re=
dhat.com/1323629
Hope this helps,
Ala

Stalled disk migration
by Nicolás
Hi,
We've done a major datastore migration recently between 2 iSCSI-based
datastores. We've successfully migrated 35 machines, however, 5 of them
seem to have stalled. All we can see in the events tab tab is:
Moving Disk bla_Disk1 from iscsi01 to iscsi02
Disks are small enough (25-27Gb) to assume this won't progress since
it's been more than 30 hs. since the migration began, other VMs took
approximately 1-1.5 hours to fully migrate a disk, so this seems to be
stalled.
The bad thing is that I can't find a way to "unstall" it. Disks are in a
perpetual "migrating" status and there's no way to stop the migration
(at least from the webadmin). I don't actually care if stopping the
migration breaks those 5 machines since they are disposable, I just need
to stop that event. I already tried restarting the ovirt-engine and it
didn't work.
Log doesn't seem to provide nothing relevant.
Is there a way to do that? I wouldn't mind if I need to modify some
record directly into the DB.
Thanks!
Nicolás

Quack,
The wiki content was already converted into the website, and remaining
broken links & co were fixed (thanks Garrett). It was merely kept in
case some content was forgotten (read-only).
The Etherpad was barely used and a pain to upgrade/maintain, so the
infra team with the last remaining user decided to close it.
They are to be removed soon. In fact we already stopped them to track
the remaining users, and no one complained. It can be restarted on
demand before the removal date.
On 2016-10-26 the resources will be purged. Backup has been made, so
nothing is lost but unless there is a good reason it won't be used.
Btw, the wiki@ mailing-list was unused and is now read-only.
If you have any concern, please contact the infra mailing-list.

documentation change suggestion / question
by Charles Kozler
Googling "ovirt windows agent" this is the first link that pops up:
http://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-w...
This doc seems non-intuitive and over complicated
Specifically, the RedHat documentation that is 4 links below is simple as
"install this package and mount the iso":
https://community.redhat.com/blog/2015/05/how-to-install-and-use-ovirts-w...
The former was updated as early as June of this year
1.) The RedHat document worked for me so I dont think oVirt 4.x cant use
the same
2.) Why have separate areas of documentation that are so different from
each other? This has caused me issues in the past whereby I found RH docs
that were much more clear and concise
3.) Is there anyone who might want to merge RH docs with oVirt docs where
the RH docs are better than oVirt?
Thanks so much for providing such a great product! I just feel sometimes
the docs are a little more developer-centric whereas the RedHat docs are
more easily readable

How to add a tcp type serial to a vm in ovirt 4.0?

Hi,
We can easily add a Serial Hardware in virt-manager, when adding
the serial, the vm's xml add these lines as follows:
.
<serial type='tcp'>
<source mode='bind' host='127.0.0.1' service='4555' />
<protocol type='telnet' />
</serial>
...
But I can't add a tcp serial in ovirt 4.0 when I create a VM, even
after I reading
http://www.ovirt.org/documentation/admin-guide/serial-console-setup/
Hope someone can help me.
Thank you
Mark

Can't add host - Failed to read hardware information
by David Pinkerton
I'm trying to add a host to a freshly built cluster.
yum install finishes, then the message " Failed to read hardware
information" is displayed - host has installation failed.
If I try to re-install I get the same message and the host goes
non-responsive.

hi all,
hmm, broker.conf is now on the shared storage and not replicated on each
host local file system. how to make changes to the conf, e.g. the notify
key?
thanks, emanuel

VMs paused due to IO issues - Dell Equallogic controller failover
by Gary Lloyd
Hi
We have Ovirt 3.65 with a Dell Equallogic SAN and we use Direct Luns for
all our VMs.
At the weekend during early hours an Equallogic controller failed over to
its standby on one of our arrays and this caused about 20 of our VMs to be
paused due to IO problems.
I have also noticed that this happens during Equallogic firmware upgrades
since we moved onto Ovirt 3.65.
As recommended by Dell disk timeouts within the VMs are set to 60 seconds
when they are hosted on an EqualLogic SAN.
Is there any other timeout value that we can configure in vdsm.conf to stop
VMs from getting paused when a controller fails over ?
Also is there anything that we can tweak to automatically unpause the VMs
once connectivity with the arrays is re-established ?
At the moment we are running a customized version of storageServer.py, as
Ovirt has yet to include iscsi multipath support for Direct Luns out of the
box.
Many Thanks
*Gary Lloyd*
