Hi, Thannx for the reply. Using two NIC sections per VM (one has eth0 bridge and the other one has eth1 as bridge) But I have a single bridge created on each of my cluster nodes i.e. eth0. When I insert NIC for private network which has bridge as "eth1", I get a error that eth1 bridge does not exist and the deployment fails.eth0 acts as a bridge between my public network and the network interfaces of VMs. This works fine.
I want that a second NIC can be added to the VMs but it fails because of the reason mentioned above.(there is no eth1 bidge).
