Sure, you are correct, it can be tricky.  And with 
linux vservers, which are not actually VMs, they
are simply a containerization technique, the 
networking simply uses IP aliases.  Each guest
gets an IP alias and using a new system call
chbind(), is bound to that IP and cannot access
the other IPs of the host.  The host, however
I believe sees all.  This is not virtualiztion 
per say and so might be different from what one 
expects, especially when it comes to the loopback
device, but I do not think the lo device is 
involved here, could it be?
