Another approach would be to use /wine,/ which works for a lot of "simple"
Windows programs, or any of its variants such as Cedega - which is intended
for playing Windows games on GNU/Linux - or Crossover Office, which is
intended to make use of MS-Office on GNU/Linux, for those who want it -
you'd be better off using OpenOffice, though. ;-)
VMware Server is free and easily installed. VirtualBox and Xen are also
available and easily installed.
I have no experience with VMware, nor with VirtualBox. On account of Xen
however, if you want to use Xen to run a virtual Windows machine, you'll
need to have hardware virtualization support.
Without hardware that supports virtualization, you can only use
paravirtualization on Xen, which requires the kernel of the "guest"
operating system to be ported to paravirtualization technology, and this is
currently only available in GNU/Linux, FreeBSD, NetBSD and OpenBSD. (I
don't know about DragonflyBSD or PCBSD.)
Xen currently also only supports either GNU/Linux or NetBSD as the "host"
operating system. The namesakes "host" and "guest" are in fact incorrect
with Xen, since Xen is only a hypervisor and runs various operating systems
simultaneously in virtual machines.
In a Xen set-up, the "host" is the virtual machine that offers hardware
access to the "guests" and has full access to their memory. Therefore,
with Xen, we normally speak of privileged and unprivileged virtual
machines. The privileged virtual machine is called "domain 0" or "dom0",
and the unprivileged virtual machines are called "domain U" or "domU". As
such, we also speak of a "driver domain" or "management domain" when
referring to "domain 0".
