[one-users] Ping vms from the host without being in the same network

[Hector Sanjuan]

When you open a VNC session, you are not openning a connection to the VM  
but to the hypervisor (host), which acts as vnc server.

I suppose that if your VM network isolation is working, you should not be  
able to ping the VMs unless you put the host on the same network.

However you can always add a second network interface to the VMs, and make  
it part of a second network along with the host. you could also add  
special rules for this iface to restrict non ICMP traffic etc I suppose.
