[libvirt-users] public IP for VM

I can't seem to figure out how to setup a public IP for the VM so we 
could use it as a second public webserver.  The host machine runs our 
primary webserver with CentOS 6.9 and one public ipv4 address configured 
on physical interface eth0.  Now i have configured a new bridge 
interface br0:

The IP settings are for a second public ipv4 address in the same 
network.  Now i setup the VM to use br0 for the NIC and set the same IP 
settings inside the VM... but it doesn't work.  The VM can't resolve any 
hosts, and if i try to ssh to the second public IP, it just sends me to 
the host machine instead of the VM.  I read the Bridged Networking 
section but it seems to want to set br0 to the public IP and not use 
eth0.  I want to use two public IP's over the same shared phys 
interface, eth0 with our first IP and br0 with the second IP for the 
VM... or another similar configuration that will have the same effect.
