Isolated POC
by Martin Schutte
Good day to all,
I am in the process of setting up an oVirt proof of concept for a client. There are some strict requirements for this POC.
Firstly the entire POC must be isolated from the network, which means no online repos.
Secondly there is a time constraint for the completion of the deployment. All to be done on bare-metal systems.
I have installed oVirt numerous times on other systems, but then I was always able to have online repos. So in short I am asking for some pointers on which repos needs to be synced offline for this to work properly. I can always go and play around to figure out which ones are needed, but I do not have the luxury of time.
Any advice or tips will be appreciated.
Regards,
Martin.

oVirt node 4.2.x - custom multipath.conf and external storage availability
by Roberto Nunin
HI all
How can I provide to my oVirt hosts a custom multipath.conf, considering
that we are using shared/mirrored FC storage from HPE 3PAR with high
availability of provided LUNs, using peer-persistance feature ?
To configure correctly this require a custom multipath.conf is required.
How I can avoid it will be overwritten during upgrades ?
Second topic:
Is ALUA feature supported also in oVirt nodes, like for standard RHEL 6/7
and/or CentOS 6/7 ?
I was digging for a while into user's digest, but not able to find focused
informations.
This is the feature needed by peer-persistance, allowing two different
volumes to be masked toward a given host with the same WWN and LUN number.
Thanks in advance

ovirt engine service needs restart after network connectivity is lost and reestablished
by g.vasilopoulos＠uoc.gr
today our network administration did some upgrades on the networking equipment, so the engine vlan went down for a while. Afterwards when it came back up 3 hosts was found as non responding, I couldn't see anything suspicious on the hosts, the problem "fixed" itself when I restarted the ovirt-engine service on the engine vm.
Another "strange" side effect is that gluster was in need of healing constantly afterwards it did heal and desynch again almost immediately, whitch was "fixed" by shutting down and starting the vm's who were up at the time of the network outage..
I've seen this behaviour once more regarding the engine service, is this normal behaviour (e.g. to make the admin check if everything is ok) or is there something wrong ?

cannot activate host
by Jiří Sléžka
Hi,
I have one interesting issue. I was asked by colleague to repair his
cluster which is part of our oVirt installation. He tried to upgrade his
host to gain 4.2 compatibility level but it fails in some cases. Never
mind, I checked it, repaired, installed upgrades and activate his hosts
with one exception.
One of hosts was stucked in finishing two tasks. One was changing
network configuration, the second was activating of this host. I have to
manually clear this tasks in database by
SELECT * FROM job ORDER BY start_time DESC;
SELECT DeleteJob('...job_id...');
SELECT DeleteJob('...job_id...');
Now this tasks are gone but still cannot activate this host.
Error while executing action:
blade01:
Cannot activate Host. Related operation is currently in progress.
Please try again later.
Host is updatet (latest 4.2 repo), rebooted, looks fine...
In tasks in UI are no tasks found (the same in db)...
What can I do now?
Cheers, Jiri

Reading an ISO image to identify the Image version and type
by Hari Prasanth Loganathan
Hi Team,
I have few ISO images, Is there a utility in oVirt which tells us which
image version it is (like windows / linux version)?
Thanks,

Re: Live Migration via NFS
by Douglas Duckworth
Hi Nir
Thanks for clarifying
We can still use NFS as export domain which can be used to move VM once
they're shutdown?
Can GPFS be used to provide shared block storage domain?

Error after rebooting ovirt-engine
by ovirt＠sandersnels.nl
Hi all,
after rebooting the ovirt-engine (4.2) i'm unable to log in to the Admin-portal anymore, because of a SerialisationException.
org.apache.commons.lang.SerializationException: org.codehaus.jackson.map.JsonMappingException: No default constructor for [collection type; class java.util.HashMap$KeySet, contains [simple type, class org.ovirt.engine.core.compat.Guid]] (through reference chain: org.ovirt.engine.core.common.action.CreateAllSnapshotsFromVmParameters["diskIds"])
The error disappears after putting in the credentials.
Irestarting the ovirt-engine service of the whole (CentOS) VM wouldn't fix it.
the server.log states a lot of these:
