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?
