You can easily do 10 or 20 with linux-vserver or OpenVZ. Even more so
if you unify the disk space, so the asterisk binary only takes up
space in memory once. We haven't found a good way to administer
linux-vserver instances with unified disk, so we don't use that
feature.

It is important to ensure that all vservers regularly get a stab at
the CPU. Otherwise you'll get jitter when you pass media through
asterisk. Transcoding can be an issue too, once you get larger call
volumes.
