<br>
I reïnstalled the 3.6 on CentOS 7 (this was the issue as vdsm is no longre build for 6.7).<br>
It's a fresh install of CentOs, only configured the adapter for a static IP and then the install of the oVirt Node.<br>
Installation goes well until following errors popup:<br>
<br>
<br>
Dec 21, 2015 3:42:45 PM<br>
Host KVM1 installation failed. Failed to configure management network on the host.<br>

Failed to configure management network on host KVM1 due to setup networks failure.<br>
<br>
Dec 21, 2015 3:42:45 PM<br>
VDSM KVM1 command failed: connectivity check failed<br>
<br>
I included both vdsm.log & supervdsm.log<br>
<br>
---<br>
<br>
I did a reboot, the ovirtmgmt was not linked to the adapter (enp3s0). Tried to link it manually which worked without hassle...<br>
<br>
So now everything seems OK. I'll test further with the 3.6 now and hope it all goes like this now<br>

Hey Dan,<br>
<br>
Thanks for your response.<br>
<br>
VDSM was the first problem when installing oVirt 3.6 on CentOS, it couldn't find the package and while browsing through the repos I couldn't find it either. So that was the first issue.. I tried compiling vdsm myself which didn't work either and I ended up
using the VDSM package under the 3.5 release. Any idea how to tackle this?<br>
<br>
If I have the time I'll try to reinstall 3.6 and note all the issues I find on the way. Can't recover those files as the server is complete messed up after my previous efforts<br>
<br>
Kind regards !<br>
Kristof<br>

<br>
Would you provide more information (logs, screenshots) about the pains of installing ovirt-3.6? These days, most of the development effort is focused on stabilizing 3.6. No further releases of ovirt-3.5.z are expected (up to horrible security bugs, etc), so
we advise using 3.6 in new instllations.<br>

<br>
ovirtmgmt should have been automatically added on top of the interface that has the IP used to add the host to Engine.<br>
<br>
Could you share your engine.log and {super,}vdsm.log from that time to understand why did it happen?<br>
<br>
Similarly, please share your ifcfg files prior to adding ovirtmgmt, and the supervdsm logs that end up with disconnection.<br>
<br>
Regards,<br>
Dan.<br>
