Virtualization, Emulator, Simulator software

VMWare Server 1.0.x
o When I need LPT1 and/or USB support
o Runs virtual machines compared with Virtual PC (except Vista)
o Need lots of network switch or to bridge more than one interface
o For cases where I need Linux on virtual machine

Virtual PC 2007 SP1
o When I need to run Windows Vista as guest OS with LPT1 support on Windows XP/W2k3/Vista hosts

Windows Server 2008 Hyper-V
o When I need to run Vista guest without a need for LPT1 nor USB support
o When I need to run Windows XP SP3 guest without a need for LPT1 nor USB support
o This virtualization product is pretty fast but need to run on 64bit capable machines and on Windows Server 2008 64bit installation.

Virtual Box
o When I run on slow host machines
o When snapshot/revert is a must for my work
o Does not support more than one bridge in Windows.
