64bit Guest and 32bit Host

[seandonnelly]

I am running VMWare Workstation 6, and I am running Windows Vista Business on an HP 8510p, which supports 64 bit computing. I also have the virtualization seting in the BIOS enabled for this system, by the way the proc type is a Intel Duo Core 2GHz with 3GB of RAM. The error I receive when starting the guest is "Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bit x86 operating system."

I am just loading this for testing purposes as we have a client running a 32bit version of Windows 2003, but has 64bit XP Pro clients connecting for print services. Any insight or direction is greatly appreciated!

Sean,

I run 64 bit guests from 32 bit XP hosts on a couple machines. I found that there is a BIOS bug on my HP workstation that causes the VT setting to get turned off after the workstation goes to sleep. You can test this by trying to start your 64 bit guest right after rebooting your host.

To work around the BIOS bug I changed the power settings in the host to not sleep.

I hope this helps.
