Question about OVN MTU
by Strahil Nikolov
Hello All,
I would like to learn more about OVN and especially the maximum MTU that I can use in my environment.
Current Setup 4.3.10
Network was created via UI -> MTU Custom -> 8976 -> Create on External Provider -> Connect to Physical Network
So my physical connection is MTU 9000 and I have read that Geneve uses 24 bits (maybe that's wrong ?) , thus I have reduced the MTU to 8976.
I did some testing on the VMs and ping with payload of '8914' was the maximum I could pass without fragmenting and thus the MTU on the VMs was set to 8942.
Did I correctly configure the test network's MTU and am I understanding it correctly that we need extra 34 bits inside the network for encapsulation ?
I have checked https://www.ovirt.org/develop/release-management/features/network... but I don't see any refference how to calculate the max MTU.

Training Video or document or training session
by info＠worldhostess.com
Can someone recommend a training video of some kind of step by step document
to do the installation and administration for OVirt? Or if someone that
wants to do a one on one online training? I would be super excited to do
online training.
I have been trying many time to install and I am sure I make some mistakes
because I can't get OVirt to work properly.
I have done numerous installations during the last few weeks.
Yours Sincerely,
Henni
