I got a server with 16GB memory, want to install 2 BIND on CentOS, one

Is it better to install 2 OS virtually and run BIND in them or run 2
instances of BIND on the same OS?
According to what I've heard, virtualization has quite high overhead in
such situations.
I mean what is the best practice to take advantage of the hardware
resources without risking having single DNS with cache and
authoritative?
You still have one server, virtualization would not change much about
this.
You can even run a single BIND instance with two separate views and
that should not affect functionality.
I suppose you are running 64bit OS, so you can have really huge cache
(>4GB)
