Memory usage inclines
by Tony Brian Albers
Hi guys,
We have a small test installation here running around 30 vms on 2
hosts.
oVirt 4.2.5.3
The hosts each have 512 GB memory, and the vms are sized with 4-8 GB
each.
I have noticed that over the last months, the memory usage in the
dashboard has been increasing and is now showing 946.8 GB used of
1007.2 GB.
What can be causing this?
TIA,
--

Ovirt Authentication extensions
by darkytoo＠gmail.com
I've seen the articles about hooking ovirt to AD and keycloak, but is there a way to hook it to something like ADFS? I'd like to have it require an MFA login and I know I can do it with ADFS.

installtion will break

Ovirt 4.3 Alpha AMD 2970WX Windows VM creation and NUMA
by Darin Schmidt
Not sure if Users is the best place for this as Im using 4.3 to test support for my AMD 2970WX Threadripper but While trying to setup a Windows VM, it fails. I have a working CentOS 7 running. Heres what I get when I try to startup the VM.
VM Windows-Darin is down with error. Exit message: internal error: process exited while connecting to monitor: WARNING: Image format was not specified for '/dev/sg0' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.

NUMA doesnt seem to resolve the issue any even if I set NUMA to be 1 and place it on a NUMA that has 12 cores and 64GB ram. I also dont fully understand NUMA because it creates 4 NUMA sockets even though technically there should be 2 correct? I dont get how NUMA is setup, but either way it doesnt help resolve any issues.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
How can I solve this?
Thanks in advance,

Network Setup after ovirt node Install and before add node to cluster
by Stefan Wolf
Hello,
I ve downloaded an installed OVIRT NODE 4.2.7.1.
During the installation I ‘ve setup a static ip (I ‘ve also tried dhcp, both work)
The installation passes and after the reboot ovirt node starts without any problems.
BUT the network is not configured.
I know https://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/ and I know
https://www.ovirt.org/documentation/admin-guide/chap-Hosts/
and now I am between these two documents
oVirt is installed but network is not configured to add it to datacenter
of course I know the scripts under /etc/sysconfig/network-scripts
do I really have do edit it manuel?
if I change ip in command line
ip a add … dev..
and ip route add …
it fails to add node to datacenter
- with one of the last version I ‘ve added the IP address in bash
- added the host to datacenter,
- after reboot readd the ip address in bash after reboot
- an then I could change network settings in oVirt Manger
What is best practices for adding a node to datacenter when the ip address is not assigned after installation
Thx shb

Ovirt Maximums
by Brian Wilson
Is there a resource available that would describe the configurable maximums for the Ovirt Engine and Ovirt Nodes.
Things like:
How many Logical Networks per host?
If one does not exist does anyone have any experiences with reaching limits that caused issues specifically with regards to the number of networks on hosts.
