oVirt nVidia vGPU driver questions
by femi adegoke
I'm on oVirt 4.2.6.
1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver?
2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7?
3) Must the vGPU driver be installed on the host & in the vm?
4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

oVirt 4.3.2 - Cannot update Host via UI
by Strahil Nikolov
Hello guys,
I have the following issue after I have successfully updated by engine from 4.3.1 to 4.3.2 - I canont update any host via the UI.
The event log show startup of the update , but there is no process running on the Host, yum.log is not updated and engine log doesn't show anything meaningful.
Any hint where to look for ?
Thanks in advance.

How to fix ovn apparent inconsistency?
by Gianluca Cecchi
Hello,
passing from old manual to current OVN in 4.3.1 it seems I have some
problems with OVN now.
I cannot assign network on OVN to VM (powered on or off doesn't change).
When I add//edit a vnic, they are not on the possible choices
Environment composed by three hosts and one engine (external on vSphere).
The mgmt network during time has been configured on network
named ovirtmgmntZ2Z3
On engine it seems there are 2 switches for every defined ovn network
(ovn192 and ovn172)
Below some output of commands in case any inconsistency has remained and I
can purge it.
Thanks in advance.

oVirt Node 4.3 Master on fc28
by femi adegoke
4.3 Master is looking good!!
A few questions:
- In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd
hosts?
- In Step #5: Bricks:
What effect does the RAID setting have?
Enable Dedupe & Compression is new?
Configure LV Cache: what do we enter for SSD? What happens if my disks
are already all SSD, do I still benefit from using this?

Expand existing gluster storage in ovirt 4.2/4.3
by adrianquintero＠gmail.com
Hello,
I have a 3 node ovirt 4.3 cluster that I've setup and using gluster (Hyperconverged setup)
I need to increase the amount of storage and compute so I added a 4th host (server4.example.com) if it is possible to expand the amount of bricks (storage) in the "data" volume?
I did some research and from that research the following caught my eye: old post "https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-..."
So the question is, if taking that approach feasible? , is it even possible an oVirt point of view?
---------------------------
My gluster volume:
---------------------------
Volume Name: data
Type: Replicate
Volume ID: 003ffea0-b441-43cb-a38f-ccdf6ffb77f8
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: server1.example1.com:/gluster_bricks/data/data
Brick2: server2.example.com:/gluster_bricks/data/data
Brick3: server3.example.com:/gluster_bricks/data/data (arbiter)

Re: Vagrant Plugin
by Jeremy Tourville
Thanks for your reply Luca,
I confirmed the cluster name, it is "Default". I even tried to run the script again and I made sure the D in default was upper case because linux is case sensitive. It still fails in the same way as before.

I am having some trouble getting the Ovirt Vagrant plugin working. I was able to get Vagrant installed and could even run the example scenario listed in the blog. https://www.ovirt.org/blog/2017/02/using-oVirt-vagrant.html
My real issue is getting a vm generated by the SecGen project https://github.com/SecGen/SecGen to come up. If I use the VirtualBox provider everything works as expected and I can launch the vm with vagrant up. If I try to run using Ovirt provider it fails.
I had originally posted this over in Google groups / Vagrant forums and it was suggested to take it to Ovirt. Hopefully, somebody here has some insights.
The process fails quickly with the following output. Can anyone give some suggestions on how to fix the issue? I have also included a copy of my vagrantfile below. Thanks in advance for your assistance!

Hello Jeremy,
Looks like you have no cluster called default in your setup. Edit your vagrant file accordingly to your setup.
