Hello,

I'm trying to setup a KVM for serving a few VPS and've got confused on bridge networking.

I have 1 ethernet card with 4 IPs; that is eth0, eth0:1 and so on.
When I setup bridge for eth0 works fine and Virtual Manager can see and assign that to the virtual machine. As soon as I do the same procedure for eth0:1, eth0:2..... then those interfaces does not getting any IP and showing just up when I run ifconfig and ofcourse are not available through Virtual Manager.

Any idea?

your problem confused me as well . it seems you have too many ethernets.

eth0:x are aliased interface to the main interface so not a a real physical interface. Are the IP's you trying to assign to the virtual machine the same as the iP's setup on eth0:x?
