[Users] Creating bridge fails on Centos 6.3 node / vdsm

Wed Sep 5 08:59:33 UTC 2012

Hello everybody,

I installed oVirt Engine on a CentOS 6.3 host (also serving repositories via HTTP and NFS, running puppet, razor and svn as well as xinetd/TFTP, NFS, DNS and DHCP). When I set up a new node with a minimal CentOS 6.3 install and then use the OVirt GUI to install vdsm on it, I get an error setting up the bridging.

As a next step, I set up the node again and installed vdsm and vdsm-cli manually before setting up the node via the GUI. This time, I don't see any errors in the event log of the node in ovirt GUI. However, the bridge is not created and the node marked as "not operational". When I click on the node and click "set up Networks", I can assign the ovirtmgmt network to eth0. When I click on OK, I get "Error while executing action Setup Networks: Internal oVirt Engine Error" in the gui. The engine.log shows the following messages:

In the installation log /tmp/vdsm-bootstrap-phase1-20120905092647.log on the node, I see these errors

Wed, 05 Sep 2012 09:27:20 ERROR    deployUtil 947 makeBridge errored:  out=Specified netmask or gateway but not ip

The node gets its IP on eth0 (backend network) via dhcp. The other nic, eth1, is currently not connected but will be connected to the frontend network and also get its IP via DHCP.

Any help how to resolve the error 'Specified netmask or gateway but not ip' is appreciated.

Kind regards
