If you needed to isolate traffic between vm's what is the best approach?  In other words I don't want them to communicate with each other. Thanks.

Disconnect the NIC in the VM's settings.

if you have vlan's on your physical network, you can trunk the connection to your VM network and then create separate portgroups for each vlan.

if you aren't using vlan's then you'll need to utilize separate uplinks/vmnics going to separate vswitches on the host.

but if you want them to sit in the same portgroup and not talke to each other...then you have to think about how you would do it if you had two physical servers connected to the same physical switch (an un-managed one) and the only way I know how to do that would be with firewalls on each server.

you can also use a local packet-filter (firewall) that drops all packs from machines in the same network.
