network settings admin interface

Networking is not configured

Sorry, forgot to add "enforcing=0" to the pxe boot config.

So it appears to be an selinux error..

restorecon on boot fails with read-only filesystem

DHCP is working, but I tried to register the node again and it gives the dreadfull "ERROR An error appeared in the UI: <InvalidData u'The field must contain an empty string or a valid FQDN or a valid IPv4 address or a valid IPv6 address.'>" message again...

Oops, forget that last comment. I put "https://" in the management server kernel argument while testing. Then it sets http://https://ovirt-engine.test.nu and that is not correct ;-)

So the error above is actually correct but should IMHO be handled by the admin interface and not drop to shell because of it...

ovirtmgmt eth0 with dchp down in engine

The ovirtmgmt interface is displayed as down in the ovirt engine

Created attachment 925671 [details]
Network ovirtmgmt not in sync

Ok sorry for all the updates but I'm debugging to save some time troubleshooting.

After the node gets registered, I see the ovirtmgmt interface (eth0) is down and not in sync. 

When I sync the network, vdsm drops the ovirtmgmt bridge and the node becomes unavailable. In the supervdsm log, I see:

root.ovirt.node.utils.network::(<module>) NetworkManager support disabled: NM Client not found (No module named gi.repository)

I cloned this bug to a different component, because you seem to describe two problems here:

1. DHCP fails to work because of a missing selinux rule (fixed in this bug)
2. Failed to register with Engine due to a different problem (addressed in the clone)

Fixed with 8e48be35e70d41027d60d93e569e9bbcbfd829bf
