[one-users] Can't access to VM through ssh

[Carlos Martín Sánchez]

Hi Andrea,

Did you manage to access the VM through ssh? or are you using VNC?

If you can't ping anything from the VM, maybe you could try adding other VMs
to that private network and check if they see each other.
Or just configure the VM template to attach a network interface to the
public network.
