[one-users] How to ping/ssh to the VMs.

[Javier Fontan]

Hello,

Can you connect to the machine using vnc and check if everything is
ok? Check that the network configuration is fine first, also the
route. Maybe the problem is the mask and you have to specify it
somehow (probably adding a parameter and modifying init.sh script)

Bye
