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

Hi Hector,

thanks! Is it also possible to add+remove the second network interface "on-the-fly", so after the vm was started?

Best regards
Jannik

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.
