Re: [ovirt-users] Network Address Change
----- Original Message -----
Hi All:
To be honest I do not see any config file in the host node
/etc/ovirt-node inside, so even I put in the global maintenance mode I
still don't know how to change the host to the new IP address.
Hey Paul,
if you are using oVirt Node (btw what version are you using?), then there are a couple of
files, there is
/etc/default/ovirt
and the well known ifcfg files:
/etc/sysconfig/netwprk-scripts/ifcfg-*
And some other paths which are handled by vdsm.
And vdsm is actually managing the network configuration when a Node is registered, that
means, it can be that any changes to the configuration files get overwritten by vdsm
again.
Maybe Toni can say something about this.
And I am also not sure if Engine will still recognize a Node, when you change the IP of
the Node, without letting the Engine know about that.
Sandro, do you know how you can tell Engine that the IP of a Node changed?
Greetings
