What I've been doing since oVirt 4 is just configuring one NIC manually when I provision the server (eg: eth0, em1, etc) and then let oVirt do the bridge setup. Once the engine is up I login to the UI and I use it to bond the NICs in whatever fashion I need (LACP or active-backup). Any time I tried to configure ovirtmgmt manually it seemed to "annoy" the hosted-engine --deploy script

Hi All,

In our ovirt 3.5 setup. i have always setup the ovirtmgmt bridge manually .
The bridge consisted of 2 nic's

I'd have /etc/vdsm/vdsm.conf list net_persist = ifcfg

When i then deployed the host from the ovirt ui or api it would install and would display the network setup correctly in the ui.

On ovirt 4. (vdsm-4.18.15.3-1.el7.centos.x86_64)
I seem unable to follow the same approach.

In the engine logs i get among other things

'If the interface ovirtmgmt is a bridge, it should be torn-down manually. '

the interface is indeed a bridge with two nics which i would like to keep this way.

On the host vdsm.log i get limited info,



when start a python terminal to obtain netinfo i get this

from vdsm.tool import unified_persistence
unified_persistence.netswitch.netinfo()

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch.py", line 298, in netinfo

    iface, = host_ports
ValueError: too many values to unpack


As it appears the line in question does not like to deal with a list of nics i think.
but either way.

Is in ovirt 4 the ability to use the ovirtmgmt bridge with multiple nics removed?

But do you need a bridge or a bond?

 

If so what can i do to stick to what we have done in the past.


Thanks.
