Migrating self hosted engine from iSCSI to NFS ?
by Matteo
Hi all,
I've a 2 hosts setup with ovirt 4, with a bunch of machines on it.
I started with an old iSCSI unit, then added a new NFS storage server
and started moving all VMs.
All VMs have been migrated over NFS (live storage migration works great!), but
now I need to move also the hosted engine, in order to dismiss the iSCSI storage.
So, what're the best guidelines to migrate ?
I suspect that simply doing live storage migration will not work :)
All backups of the hosted engine are available.
Thanks!
Matteo

Get Involved with the oVirt Project! Autumn 2016 Edition
by Sandro Bonazzola
Hi,
Have you got some free time? Do you want to get involved in the oVirt
project?
Do you like the idea of having fresh disk images of your favorite
distribution in the oVirt Glance repository?
You can help by testing existing online images ensuring they work with
cloud-init,
or creating one yourself and report your success to devel(a)ovirt.org.
We'll be happy to upload the images once these are ready.
Do you like Debian? Do you have some programming or packaging skills?
Help getting Vdsm running on it! There is some on-going work [14
<https://www.ovirt.org/develop/release-management/features/debian-support-...>]
on inclusion of Vdsm into Debian.
We wish to test and fix Vdsm Debian packages to make them working before
the next Debian freeze.
You can find all current Debian work (Vdsm and related packages) in Debian
git repositories [10 <http://git.debian.org>].
You can follow the progress and participate on oVirt development mailing
list [11 <http://lists.ovirt.org/mailman/listinfo/devel>].
Here are some bugs you can try to help with:

Are you great at packaging software? Do you prefer a distribution which is
currently unsupported by oVirt?
Do you want to have packages included in your preferred distribution? Help
getting oVirt ported there!

Ovirt/Gluster replica 3 distributed-replicated problem
by Davide Ferrari
Hello
maybe this is more glustefs then ovirt related but since OVirt integrates
Gluster management and I'm experiencing the problem in an ovirt cluster,
I'm writing here.
The problem is simple: I have a data domain mappend on a replica 3 arbiter1
Gluster volume with 6 bricks, like this:
Status of volume: data_ssd
Gluster process TCP Port RDMA Port Online Pid
------------------------------------------------------------------------------
Brick vm01.storage.billy:/gluster/ssd/data/
brick 49153 0 Y
19298
Brick vm02.storage.billy:/gluster/ssd/data/
brick 49153 0 Y
6146
Brick vm03.storage.billy:/gluster/ssd/data/
arbiter_brick 49153 0 Y
6552
Brick vm03.storage.billy:/gluster/ssd/data/
brick 49154 0 Y
6559
Brick vm04.storage.billy:/gluster/ssd/data/
brick 49152 0 Y
6077
Brick vm02.storage.billy:/gluster/ssd/data/
arbiter_brick 49154 0 Y
6153
Self-heal Daemon on localhost N/A N/A Y
30746
Self-heal Daemon on vm01.storage.billy N/A N/A Y
196058
Self-heal Daemon on vm03.storage.billy N/A N/A Y
23205
Self-heal Daemon on vm04.storage.billy N/A N/A Y
8246
Now, I've put in maintenance the vm04 host, from ovirt, ticking the "Stop
gluster" checkbox, and Ovirt didn't complain about anything. But when I
tried to run a new VM it complained about "storage I/O problem", while the
storage data status was always UP.
Looking in the gluster logs I can see this:

Now, how is it possible to have a split brain if I stopped just ONE server
which had just ONE of six bricks, and it was cleanly shut down with
maintenance mode from ovirt?
I created the volume originally this way:
# gluster volume create data_ssd replica 3 arbiter 1
vm01.storage.billy:/gluster/ssd/data/brick
vm02.storage.billy:/gluster/ssd/data/brick
vm03.storage.billy:/gluster/ssd/data/arbiter_brick
vm03.storage.billy:/gluster/ssd/data/brick
vm04.storage.billy:/gluster/ssd/data/brick
vm02.storage.billy:/gluster/ssd/data/arbiter_brick
# gluster volume set data_ssd group virt
# gluster volume set data_ssd storage.owner-uid 36 && gluster volume set
data_ssd storage.owner-gid 36
# gluster volume start data_ssd

we have a great news regarding Ansible modules for oVirt 4 management. As
you may have already noticed in [1] and thanks to Ondra's hard work we were
able to push following modules into Ansible 2.2:
ovirt_auth
- manages authentication against oVirt engine instance
ovirt_vms
- manages VM lifecycle
- manages VM's disks and NICs (more advanced disks and NICs management
will be provided by specialized modules)
ovirt_disks
- manages VM's disks and floating disks
You can find more details about those modules at [2].
But this is not end of our effort, we are working on other modules that
should cover most of functionality provided by oVirt SDK and hopefully will
be included in Ansible 2.3 (more info also at [2]).
Any feedback on those modules would be very welcome.
Regards
Martin Perina

oVirt 3.6 and Fedora 24: How to change display resolution?
by Richard Harmonson
I am unable to change the display for a Fedora 24 Workstation using Gnome
3.20 from its default 1024 x 768. I, also, tried a number of spins but the
behavior persist. Installing on a physical desktop does not reproduce the
symptom. Installing CentOS 7 does not reproduce the symptom.
Under the virtual machine "Applications" it shows:
kernel-4.7.4-200.fc24
ovirt-guest-agent-common-1.0.12-3.fc24
xorg-x11-drv-qxl-0.1.4-7.fc24

oVirt 4.0.x - hosted-engine was not starting properly

Hey All,
Since updating to 4.0.x of oVirt, I have had an issue with my hosted =
engine. After a some poking around, I think I have figured out my issue =
and thought I would share to see what others think.
The issue has existed with 4.0, 4.0.1, 4.0.2, 4.0.3, and still exists in =
4.0.4.
Description:
When my hosted engine starts it reports that it is in a degraded state =
with 7 or 8 services still not started when I run systemctl status. It =
takes about 6 or 7 minutes to eventually start all the services and come =
online. If I don't set my cluster to Global-Maintenance mode it =
eventually thinks that my hosted-engine needs to be rebooted and =
restarts it before it can start everything.
Solution:
I realized that Apache was the culprit and found that the proxy to the =
ovirt-engine in /etc/httpd/conf.d/z-ovirt-engine-proxy.conf has a super =
long timeout with many retries. I changed the settings and now =
everything works for me.
-> Before change:
<LocationMatch =
^/(ovirt-engine($|/)|api($|/)|RHEVManagerWeb/|OvirtEngineWeb/|ca.crt$|engi=
ne.ssh.key.txt$|rhevm.ssh.key.txt$)>
ProxyPassMatch ajp://127.0.0.1:8702 timeout=3D3600 retry=3D5
<IfModule deflate_module>
AddOutputFilterByType DEFLATE text/javascript text/css =
text/html text/xml text/json application/xml application/json =
application/x-yaml
</IfModule>
</LocationMatch>
-> After change:
<LocationMatch ^/ovirt-engine($|/)>
ProxyPassMatch ajp://127.0.0.1:8702 timeout=3D5 retry=3D2
<IfModule deflate_module>
AddOutputFilterByType DEFLATE text/javascript text/css =
text/html text/xml text/json application/xml application/json =
application/x-yaml
</IfModule>
</LocationMatch>
If I read the timeout settings correctly, it will wait 60 minutes with 5 =
retries. 5 hours is way too long for my little server to hold onto all =
those apache processes. The change I made allows for there to be an =
error, and also releases apache's hold on the process. Once everything =
is ready, apache is ready to serve requests and everything/everyone is =
happy. Before making the change, I just get a whitescreen in my browser =
and then nothing works until I restart Apache (or I end up in an endless =
loop of ovirt-ha services restarting my hosted-engine.
I noticed that this setting reverts to the original setting, so oVirt =
must be writing this file. Perhaps these number can be changed in oVirt? =
If not, I will just setup and ansible play to revert the settings with =
working values and restart apache on my engine.
:-)
Cheers,
Gervais

vioscsi.sys BSOD with Win 7
by Cam Mac
Hi,
I'm running oVirt 3.6.3.4-1.el7.centos and when I install a Win 7 guest
VM, using VirtIO disk, networking etc, it goes through the install process
ok, but blue screens upon boot with a vioscsi.sys error (attached). I have
tried the official version ovirt-guest-tools-iso 3.6.0 0.2_master.fc22, as
well as some earlier and later versions. I am using a PXE boot method with
a Windows deployment server, which has the drivers from the oVirt tools ISO
installed (indeed, it picks up the drive and networking and I can see it
installing the drivers). I have tried with the generic IDE and rtl8139
config on the guest, and it also fails with the same vioscsi.sys error
after rebooting upon finishing installation even though I'm using IDE as
the disk driver.
I have uploaded a win 7 x64 ISO and tried installing that, and it loads the
VirtIO viostor driver (using the method at:
https://www.ovirt.org/documentation/how-to/virtual-machines/create-a-wind...),
and even manages to partition the disks, but fails to install on the disk
(screenshot attached).
I've tried temporarily removing the vioscsi files from the install server
as a last resort, but as expected it fails to install properly, though I
thought it used the viostor driver instead.
Thanks for any help.
Regards,
Cam
