Base Windows virtualization requirements

This has been announced before – but I get asked about it a fair bit – so I thought I would take the time to mention it explicitly.  One of the key requirements for Windows virtualization (the new virtualization technology being provided by Microsoft as part of the Longhorn Server wave) is that we will be requiring the presence of an Intel EMT64 processor with VT support or an AMD64 processor with (codename) Pacifica support.  We will not be supporting 32bit only processors, or processors without hardware virtualization support.  So if you are buying new server hardware with the thought to run Windows virtualization technology on it when it is released – please make sure that the processors meet this base functionality.
