<div dir="ltr">Nir -<div><br></div><div>At this time I cant do anything. I succesfully upgraded the CentOS 6.7 engine VM to 3.6 but after migrating it to a new node packet loss on the VM is significant.

What can I send to attach here? As of now I cannot add any new systems because the ovirt-engine is pretty much dead. I am learning towards my only option is to rebuild everything on CentOS 7.

I am in the process of upgrading my nodes to 7 although since the upgrade of my engine to ovirt 3.6 the network on the VM itself has become very instable. Ping packets are unresponsive from time to time and I cannot get a reliable SSH connection. My guess is something inside ovirt 3.6 does not like to run on a 3.5 node (expected I guess) and something is occurring inside of the brains somewhere.

<br>
</span>If you want to use official packages, yes.<br>
<br>
But this is free software, so *you* are free to build your own package.<br>
<br>
The patches you need are in the ovirt-3.5 branch:<br>
<a href="https://github.com/oVirt/vdsm/tree/ovirt-3.5" rel="noreferrer" target="_blank">https://github.com/oVirt/vdsm/tree/ovirt-3.5</a><br>
<br>
You clone vdsm, checkout this branch, and build it. But you will have to support<br>
it yourself, because we are focusing on refining 3.6 and working on 4.0.<br>
<br>
Unless you cannot upgrade to el 7 or fedora >= 22, I recommend to upgrade your<br>
hosts and use official packages.<br>

</span>Yes<br>
