[TriLUG] machine comparing... possibly OT

You really don't need a load of hardware for a VM solution, or money for 
that matter.


VMware has released VMWare server for Windows or Linux as free, as in 
beer, not speech, but we'll take the small victories. In a VMWare 
session you can run only one Virtual machine, that shouldn't take a lot 
of overhead.  I'm guessing that a system with 512 MB RAM can run a host 
os, say Fedora, and a VM with Windows XP fairly well, not under any real 
load, but it doesn't sound like that's an issue.  You can map physical 
serial ports to VM instances so they present as if they are real hardware.

Perhaps you can't go there today, but I'd work that angle hard.  Invest 
today, about $1K and not spend $500 later if the system needs to be 
reloaded again.  Not to mention that it would take just a couple of 
minutes to bring up a new instance of the VM from saved files.

Any way you go, good luck.
