You should be able to use that same bridge for your other virtual machines. I have a host running three virtual machines and only one bridge. I am using KVM for virtualization, but the same should apply in most instances.

Think of a bridge as it's own interface. A NIC could be a member of several bridges. However, if you can simplify things and use the same bridge you all ready set up. You can add multiple machines to the same as grim stated.

That would depend on what virtualization method you are using and how you are setting up your vms. Here is an example of something that you might use to set them up, but these items would depend on your environment.

Code:

virt-install \
       --name kvm2 \
       --vcpus 2 \
       --ram 1000 \
       --disk path=/dev/mapper/VolGroup00-LogVol03  \
       --network bridge:br0 \
       --arch i686 \
       -l nfs://10.1.1.212/nfsexport/rhel5.4-server-i386-is/
