"We currently run engine on CentOS 6 as CentOS 7 was not yet supported. We plan on
migrating it to a CentOS 7 machine.
Our nodes are currently CentOS 6 but are planning to migrate to CentOS 7. (For the nodes a
checkbox for each distribution would be better than the
radiobutton, as you can have multiple clusters with different distributions)."

"We use atm local storage.
Current running vm count is over 100.
I'd like to use EL7 platform in the future, but I'm uncertain how to best
upgrade everything with a minimal downtime.
we currently run ovirt-engine 3.3.3
we will stick with EL platform and not switch to fedora based, because
we need the improved stability.
we also do not upgrade to dot zero releases as these introduced
some breakage in the past (regressions).
I hope this gets better with future releases.
Keep up the good work!

"Cloud used for CI purpose, made from about ""old"" 50 desktop
PCs (and still growing) with Celerons, i3, i5 and few i7. VMs are

Jenkins (2GB-6GB/2-4cores). Some resources are utilized for cloud's services like vpn,
zabbix, httpd, etc. As storage we use MooseFS!"

"This is a sample config for the few installes I have performed, but ideal for a

--
"I think that we really need more troubleshooting tools and guides more than
anything. There are various logs, but there is no reason why we
shouldn't be publishing some of this information to the engine UI and even automating
certain self-healing.
The absolute most important feature in my mind is getting the ability to auto start
(restart) VMs after certain failures and attempting to unlock
disks, etc.. VMware does a tremendous amount of that in order to provide better HA. We
need this."

"Have FC only. Using SVC. Behind it now DS4700. Going to have other storages too.
This is BYOD.

Combo glusterfs storage and vm hosted nodes. Will be migrating engine to centos 7 at some
point. Wish libgfapi was properly supported now that it's
feasible.

I use oVirt since version 3.0. The evolution of this project is outstanding. The biggest
unsolved problem is that there is no good backup solution for
oVirt.

Modest server with all-in-one oVirt installation.

"oVirt is for Testing actually, I should say validate. We use Xen Open Source and
plan to migrate to oVirt during this year."

"Create multiple VM using ovirt in order to provide platform as a service in my
campus environment.
All the VM(s) created will be used to run web based application for the purpose of final

I did this only on 1 physical server as we currently have the limitation on the hardware
part."

"small lab environment, ~10 nodes, ~20-30 VMs. "

Ovirt 3.4.4 with 16 VDSM Nodes and 170 virtual machines. We currently use Direct attached

"IBM Blade Center.

"We started looking at OVIRT a while ago and it had come a long way. My only
objection to migrating it into our production is the issues we have with
the network interfaces (bonded VLAN tags on the mgmt) and their removal on boot/reboot.
Other than that we have fully tested multi-cluster glusterized
environments successfully.
Again outside of the networks the only other feature I would suggest is gluster storage
for the hosted engine. "

Storage is ZFS shared over NFS via dual 10 gbit links. Running 15 nodes now.

We will upgrade up CentOS7 soon
--
"2 FC datacenters, 4 VNX SAN, 2 4To Lun, 25 hosts on 2 physical sites, 180 centos
server vms. We used to recycle all our old servers (1950, 2950, G6
etc..) to get additional vCPU and RAM, but it has no more interest since we got 4 new
r630 chassis with 128 Go of RAM and 40 vCPUs per server. So the
goal is to reduce the number of hosts when keeping the same capacities."
--
"2 production setups in different DC, beginning their history from ovirt-3.2, thus
centos6 and no hosted-engine.
dell m1000e bladesystem + fc storage in first one; hp dl580 g7 + fc storage in second.
~150 vms in each"

Storage is ZFS shared over NFS via dual 10 gbit links. Running 15 nodes now.
--
"Just started using Ovirt, we're using supermicro microcloud servers with 32GB
memory and quad core E3-1241v3 Xeons.
We're using the jenkins builds of ovirt-node since there isn't a recent ovirt-node
build. "
--
Hyorvisor used also as replica glusterfs nodes.
--
"We run about 20 VMs on 3 proliant machines with a msa backed shared storage.
We have migrated dec/jan to oVirt and I am a big fan of the virtualization solution. We
ran VPS before on Virtuozzo, but it did not provide out of the
box HA.
The only thing I was missing is some way of automated backups.
We have finally bought a proprietary backup solution ( R1soft CDP ) to run within the VMs
to have disaster and file backups.
Overall a great product!
