Is there a way to create a private isolated network between vm like that of
default virbr0 created  in case of virt-manager (with 192.168.122.0)  with
out making any bridging with actual interface?

i dont want to install virt-manger or use virt-manger to create private
bridge.

*platform:*
Xen 4.1.2 running with ubuntu 12.04 as dom0.

Installed *bridge utilities* but virbr is not showing up.

can any one please tell me how to create virbr0 like bridge  without
installing virt-manager.

Yes.
To create a bridge without enslaving any physical network interfaces to 
it, you can do it via /etc/network/interfaces file. Just define a bridge 
as usual, but specify "bridge_ports none" instead of attaching any
ethX
to it.
Some people prefer using "dummy0" instead of "none".

You can create the bridge(s) manually, using your OS native means.

It is supposed not to. It''s just the tool, the actual configuration is 
still need to be done.
