I'd check the VMware guide to see if the server/cpu is supported for ESX 4. ESX4 is itself 64-bit so if the hardware supports it, odds are really good it will support 64-bit guests.
What are your current servers?

CPU and BIOS have to support it. I was hoping someone had some tips on figuring this out BEFORE buying that shiny server off of eBay.

However, there are certain BIOS setting requirements as well which might be your current problem. They have a support doc on running 64 bit guests that says what is required. -------------------------- Sent using BlackBerry ________________________________ From: Philip Brothwell <philip.brothw...@gmail.com> To: NT System Admin Issues <ntsysadmin@lyris.sunbelt-software.com> Sent: Wed Dec 30 13:26:14 2009 Subject: Hardware for 64 bit guest OS in Vmware Hi, Anyone know of a easy way to tell if a computer will be able to run a 64 bit guest in Vmware? I have two 64 bit machines in my home lab, one running ESXi and one running Vmware Server. Neither will run a 64 guest so I'm looking to upgrade to do some testing with 2008 R2.
