No

Not with Xen, KVM, or Hyper-V.
Possible with Vmware or Virtualbox, but only if it's 32bit x86.

I assume you want to run Windows 2003 Itanium on top of plain x86
servers? Then no, it's not possible.

The million-dollar question :D
Some companies play lots of money to consultants for that. Depends on
who you ask, you'll get different answers. As for benchmark, try
http://searchservervirtualization.techtarget.com/search/1,293876,sid94,00.html?query=benchmark&x=0&y=0
The fourth entry is quite interesting

Basic suggestions: install special disk/network drivers for whatever
solutions you use. For Xen, this will be either Citrix PV drivers or
GPLPV. For vmware/vitualbox, this will be thir "guest additions".
However, I/O-intensive server might not be the best one to virtualize.
Unless, of course, if you already know that those 5 servers are
lightly-used (only 10% utilization, for example).
