[Dshield] VMware

I have just verified this and yes. To run a 64Bit OS you need a 64 Bit
processor on the Host. The same goes with Virtual Processors (2), you
need to have a Dual Processor host, although Hyper threaded machines
with a single processors act as a dual so most of the newer Pentium4's
will be fine.

Moses,

I guess what you mean by native and virtual is that, as long has the 
host OS & VMware software is on hardware that supports the underlying 
feature (dual core and/or 64 bit processor) then it is possible to build

a VM that has the same virtual machine support. On the other had I would

not expect VMware WS5.5 to support, say a 64 bit vm on an underlying 
machine that is a 32 bit processor? Is this interpretation correct?

John Holmblad
