CentOS virt - Sep 2011 - Network and IP's

Hi,

When "playing" with Cent OS 5.x Virtualization, I could have a host
with
IP:192.168.10.40 and the guests with IP's: 192.168.10.41, 
192.168.10.42... an so on.

But now after installing Cent OS 6.0 as a host, I can't figure out how 
to make my guest get the same IP's.

My host is still 192.168.10.40, but the 1. guest i make, get an IP of 
192.168.122.x !

I can see something in virtual-manager concerning virtual-networks. It 
looks new compared to COS 5.x.

Is it not possible ?

Regards Thomas

Sounds to me that you have not created the virtual bridges/networks that are on
the the other host.  Is the output of virsh net-list the same?

I'm probably missing something here but doesn't editing ifcfg-ethX in
the guest give them the required IP or is virt-manager overriding
those settings?
