[Users] setupNetworks failure - Host non-operational

Hi All, I have a multi-VM setup, where I have ovirt engine on one VM and VDSM host on another. Discovering the host from the engine puts the host in Unassigned state, with the error saying 'ovirtmgmt' network not found. When i select setupNetworks and drag-drop the ovirtmgmt to setup over eth0, i see the below error in VDSM & host goes to non-operataional state. I tried the steps mentioned by Alon in http://lists.ovirt.org/pipermail/users/2012-December/011257.html but still see the same error ============= dump from vdsm.log ================ MainProcess|Thread-23::ERROR::2013-01-22 18:25:53,496::configNetwork::1438::setupNetworks::(setupNetworks) Requested operation is not valid: cannot set autostart for transient network Traceback (most recent call last): File "/usr/share/vdsm/configNetwork.py", line 1420, in setupNetworks implicitBonding=True, **d) File "/usr/share/vdsm/configNetwork.py", line 1030, in addNetwork configWriter.createLibvirtNetwork(network, bridged, iface) File "/usr/share/vdsm/configNetwork.py", line 208, in createLibvirtNetwork self._createNetwork(netXml) File "/usr/share/vdsm/configNetwork.py", line 192, in _createNetwork net.setAutostart(1) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2148, in setAutostart if ret == -1: raise libvirtError ('virNetworkSetAutostart() failed', net=self) libvirtError: Requested operation is not valid: cannot set autostart for transient network MainProcess|Thread-23::ERROR::2013-01-22 18:25:53,502::supervdsmServer::77::SuperVdsm.ServerCallback::(wrapper) Error in setupNetworks Traceback (most recent call last): File "/usr/share/vdsm/supervdsmServer.py", line 75, in wrapper return func(*args, **kwargs) File "/usr/share/vdsm/supervdsmServer.py", line 170, in setupNetworks return configNetwork.setupNetworks(networks, bondings, **options) File "/usr/share/vdsm/configNetwork.py", line 1420, in setupNetworks implicitBonding=True, **d) File "/usr/share/vdsm/configNetwork.py", line 1030, in addNetwork configWriter.createLibvirtNetwork(network, bridged, iface) File "/usr/share/vdsm/configNetwork.py", line 208, in createLibvirtNetwork self._createNetwork(netXml) File "/usr/share/vdsm/configNetwork.py", line 192, in _createNetwork net.setAutostart(1) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2148, in setAutostart if ret == -1: raise libvirtError ('virNetworkSetAutostart() failed', net=self) libvirtError: Requested operation is not valid: cannot set autostart for transient network
