you should make sure that you utilize unification
in this case, as it will probably be the best shared
resource in your setup (only config files will differ)
so given the server is configured well, and all guests
are 'idle' you can probably put 300+ there

here some tips _for your_ setup:

 - make sure to use unification (saves disk space
   and most important memory for mappings and caches)
 - reduce the number of guest processes, maybe even
   to a single process (the VoIP app) plus a fake init
 - configure higher HZ values (1000Hz) disable
   preemption, get apic running, configure the hard
   cpu scheduler for timeslicing

HTH,
