Re: [Users] Centos 6.5 and bonding: "A slave interface is not properly configured"
Hi Karli,
Normally we configure the host's default gateway on the ovirtmgmt network.
If your engine is in the same subnet as all of your hosts, then it's not to define
a getway on the ovirtmgmt network.
From 3.3, you can define gateways on the other networks. These will be
used via
source routing. For example, if you set a gateway on the display network,
but leave
the gateway blank for the ovirtmgmt network, then you'll see that 'ip route'
won't
list a default gateway. However, we configure source routing so that all traffic
coming in to the display network on the host, will be returned via that network's
gateway.
You can view source routing rules via:
ip rule
Then ip route show table %s, for each table listed in ip rule.

Yes, and that's what happening whenever you make changes to
ovirtmgmt via Vdsm.
To tell you the truth, that makes me rather uncomfortable since we have
set up our ovirtmgmt on a non-routed, "black" net, only used for _mgmt_
(thought that was the point). The display network is set up on a another
logcal network, a routed net, which is where we also have the default
gateway. Is this now a "wrong/bad" way to go about it?
