rhev3.0 ,can not attach a different network to eth0
I had installed rhev3.0 , hypervisor6.2-201110-- , the hypervisor has 2 network adapters , now I want to create 2 bridge networks ,one attach to eth0 , another attach to eth1 , bridge RHEVM is the hypervisor management network bridge that attached to eth0 ,too
every network has a unique vlan tag
I can create several different networks in datacenter , and attach to a cluster in the datacenter , then try to attach network to eth0 , only rhevm could be used .
when try to attach network to eth1 which is not the hypervisor manangment adapter , all networks except the rhevm could be used .
how could I attach a another network to the rhev management adapter ?

You have to do this manually on the host at the minute. The RHEV network management is pretty basic, so you'll need to create the tagged bonds and bridge them yourself.
Then you can place it on the same interface with other logical network.
Please see:
https://access.redhat.com/kb/docs/DOC-22959 for the supported network configurations. This applies to all the logical network, rhevm inclusive.

Explains how to configure VLAN tag on the rhevm network, this is the important part, since as James had mentioned, it's the fundamental network of a RHEV system, thus requires a specific sequence in order to manipulate it without loosing connectivity to the hosts while you are doing so.
This problem is really annoying. Been fixing this using
- injector virtual machine (for closed environment for some customers)
- vaccinate scripts
A sample script is here (from my personal lab):

maintenance + remote console is a plus ...
Hope this helps,
