OKD / Openshift under oVirt
by michael＠wanderingmad.com
I have ovirt currently running with 3 hyper-converged nodes, and loving it. I've had some issues with kubernetes and would prefer to try out openshift / OKD, but the trick is i'd like to do it in a fault-tolerant way, with a load balancer, 2 masters and 3 works, but I can't seem to find a good way to do it, is there anyone that can offer help? I tried using what was posted to the blog, but it was a single-node install and was never updated with part 2.

Timestamp offset in engine.log
by Ian Fraser
Hello,
I am trying to follow the instructions for installing the metrics store
and a prerequisite is ensuring the timestamps in /var/log/ovirt-
engine/engine.log include a UTC offset (at bottom of this page:
https://www.ovirt.org/documentation/metrics-install-guide/Introduction.html
). Mine currently do not (i.e. they look like "2019-03-07
14:14:23,223Z").
"timedatectl | grep -i 'time zone'" shows "Time zone: Europe/London
(GMT, +0000)"
Can anyone please tell me how to change this timestamp format to
statisfy this prerequisite?
Thanks
Ian Fraser

https://bugzilla.redhat.com/1638835 looks like there is at least
kernel 3.10.0-957.3.1.el7.x86_64 required.
Can you please check if upgrading to kernel solves the issue for you?
I expectect at least kernel 3.10.0-957.5.1 to be availible.

Re: Infiniband Usage / Support
by Douglas Duckworth
You can change the MTU in the network config in oVirt engine. The management portal. Go to clusters then networks or something like that. You can then modify the MTU.
MTU can also be set manually in network scripts on the host but you need to define this in the engine. At least this is how I got Infiniband working. I can send screenshots on Monday.

Some details, step by step.
Install OS, Install OFED,
Create Bond for ib0 and ib1 - bond0
Set IP to bond0, and MTU to 65520.
Add Host to oVirt Cluster
At this moment of time everything is Fine.
Next step.
Assign New network to bond0, oVirt set MTU to 1500, and ... That is all. No storage, No IP. I can't change MTU to 2044 or 65520 and can't assign IP to IB interface.
From system perspective i do understand why.
oVirt Creates new bridge using brctl - and brctl didn't support IPoIB, but how can i change it back to original config?

oVirt 4.3 and AMD Opteron G3 CPU
by Jiří Sléžka
Hi,
I know, old AMD Opterons G3 are unsupported in oVirt 4.3 but anyway, is
there a way to switch cluster to 4.3 mode with these old CPUs? On the
other hand 4.2 mode is no problem, I just would like to test new stuff
(on legacy hw ;-)
Cheers,

Re: oVirt Performance (Horrific)
by Strahil
Hi Drew,
During my tests on gluster v3, using 'disable.nfs: false' and using that as ovirt storage brought maximum performance for my 1 Gbit/s network.
Can you try using NFS and if it works well, you can disable nfs and get NFS Ganesha up and running.
It seems that FUSE in gluster v5 is performing way better, but still it is not the optimal solution.
Best Regards,
