The interface from the host OS to the guest also needs to be part of
the bridge. For instance, in Linux KVM, the "tap" interface presented
by the host OS has to be part of the bridge. The guest OS can assign
the IP you want and traffic passes bidirectionally. Don't know about
other Virtualization platforms.
Can you share the output from "/sbin/brctl show"?
This is what my setup looks like (from a Debian setup)
$ /usr/sbin/brctl show
bridge name bridge id STP enabled interfaces
br0 8000.00262d5588d1 no eth0
tap1
tap3
br1 8000.aa9267231e88 no tap2
tap4
