Installation Help
by bilal.ahmed＠kfueit.edu.pk
Dear Sir
I have successfully installed the ovirt engine and ovirt node separately on
two machines and I have accessed their web portals as well . But I am facing
a problem in its initial configuration that I am unable to add a host and
its installation fails . I am using default data center and default cluster
. Could you please guide what can be the issue , credentials are correct .
I have tried to add both the ovirt engine and ovirt node as a host but
failed.

Unable to revive host after a reboot
by Julius Schwartzenberg
Hi,
I recently had to shutdown my oVirt system which contains both the
engine and the host. After it came back up, the host was not able to
initialize anymore from the oVirt UI.
First it kept getting stuck in a loop with setting "ExecutingStarted:
Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode."
This was being repeated over and over again. It also gave this error:
Host pc331 does not comply with the cluster Default networks, the
following networks are missing on host: 'ovirtmgmt'
Even though I am using that interface (ovirtmgmt) to access the system
and 'ip addr show' shows that it's set up properly.
I tried some more things, including upgrading the host, When I do
that, the status changes to 'Installing' and later to 'Install
Failed'.
Here are the engine.log, vdsm.log and ovirt-host-deploy*.log:

Any idea what is going wrong (what I'm doing wrong) and how to solve it?
Thanks in advance!
Best regards,
Julius

Switch from nightly to stable
by Demeter Tibor
Dear users,
Around ovirt 4.2.2 after a bug I had switch to nightly from stable. Its was do applied only on the engine, not compute nodes.
But now I would like to switch back to stable branch.
How is safe that? I just need do remove the nightly repo and update? Need to apply a yum update * before or not?
Please describe me what is the safe procedure.
Thanks in advance,
Regards,
Tibor

Possible to use Console via Mac web browser?
by Jayme
I recall in the past (on a bit older of an oVirt build) I was able to
launch VM consoles from my web browser. I believe it may have been using
spice html5 at the time, is this still possible? Currently launching
console downloads the typical .vv file.
What is currently the best/easiest method to access VM consoles using
MacOS?

uploading ISOs
by William Dossett
Hi,
Before I go to the work of making my iso's available to the ovirt-engine so
I can use the iso uploader cli.
I haven't worked with ovirt for a while and the documents still refer to an
ISO domain and engine-iso-uploader the former which I understand is not
required now, just wondered if there was any easier way to upload through
the web UI maybe? I noticed an upload button under images. could that be
used for ISOs?
I remember that was something that put me off slightly working with Ovirt
last time was the number of steps I had to take to get an ISO available to
build a VM from, but if that's still the way I will soldier on.
Thanks

Trouble connecting to IDRAC7
by Jayme
I just enabled power management/fencing successfully on two of my hosts
(Dell poweredge R720s with Idrac 7) but am failing to add the third. I
enter the IP and user/pass like the others, it takes 15 seconds or so they
spits out "Test Failed: Internal JSON-RPC error"
I tried resetting the IDRAC on that server. I can also ping it and access
it fine in a web browser. I can ping it from the host as well.
Is there any configuration in IDRAC that could be blocking the fence
attempt or any logs in oVirt I can look at to figure out what might be
happening with the connection?
I see there is a "fence_idrac" command on the hosts but unsure what
switches to use with it to test.
Thanks!

template disk attribute in version 4 restapi
by like.ma＠cs2c.com.cn
Hi All,
In the restapi of version 3, there is bootable attribute in disk. But in version 4, the bootable attribute is removed from disk. For vm i can get bootable attribute from diskattachment. But there is no diskattachment in template. So, is there any way in the restapi of version 4 that i can know if the disk of the template is bootable or not?
Thanks
Regards.

Data Recovery from snapshot
by Jim Kusznir
Hi:
With yet another gluster disk failure / gluster collapse, it appears I lost
the "main" backing image for one of my vm servers. I have snapshots still
in tact (or at least, appear to be), but the main image is gone.
The main server process stores a backup at regular intervals in its disk,
and that would have been changed data, so it would be in the snapshot
rather than the base image. Is there any way to recover this one .tar.gz
file from the snapshot with the missing main image? This is a backup of
dynamic data, and without it, I will have lost several customers data, some
of which cannot be recreated/regenerated.
it also appears that my backup (gluster geo-replication) did not work (had
crashed a while ago, and has a very old backup of this image).

[No question] NFS disabled, hosts wandering tearful
by Nicolas Ecarnot
Hello,
This is a simple testimony about what happened yesterday in one of our DC.
This DC runs on a dedicated bare-metal engine, oversized compared to the
need, thus I've added a NFS service on it to host a small storage domain
and the ISO storage domain.
Yesterday, after having received the colorful announce about the 4.2.5
version, I decided to upgrade.
As our engine was still on a CentOS 7.4, I first upgraded its OS version
to 7.5, then reboot. Smooth.
Then I followed the very usual oVirt engine upgrade path. Smooth.
Eventually, I upgraded the hosts with ovirt-ansible-cluster-upgrade as
usual.
The result was frightening because the hosts were put in maintenance,
upgraded, back to life, seen unavailable, unreachable, connecting,
alive, rebooted, then back to another turn and looping...
During this, the SPM role was obviously jumping around, and that did not
help the debug.
In the end, it appeared that something during an upgrade stopped and
disabled the NFS service. My hosts partially relied on it, so after
having restarted the NFS service, all came back to life.
The NFS disabling may come from the CentOS upgrade, except if someone
tells me it could come from something on the oVirt side?
I'm sure the RH people will advice me not to run NFS on the engine, but
apart this event, I had no trouble doing this in years.
Regards,

Adding custom network filter to oVirt
