When I try to power on the virtual machine in esxi 4.1 I get the following message:

msg.cpuid.noLongmodeQuestionFmt:This virtual machine is configured for 64-bit guest opeating systems. However, 64-bit operation is not possible.. This host does not support VT. For more detailed information see http://vmware.com/info?id-152.
Continue without 64-bit support?Y/N......

I have verified that Hyperthreading is enable in the BIOS. I am trying to boot to a x64 windows 2008 r2 iso in the data store and keep on receiving this message prior to the VM starting up.

Thanks and regards,

Robert

VT means Virtualization technology.  You might drop into the BIOS/CMOS menu and make sure that the VT is enabled.

You need to have Intel - VT (or AMD-V) virtual technology enabled in the BIOS. That enables you to access/install 64-bit VMs.

VT also needs newer processors (Core 2 generation and newer on Intel).  Its basically the hardware extensions for virtualization.

I know the G5 is supported because...well, I have all of them in my virtual infrastructure :)

It will not work, the G4 does not support Intel VT and thus you're stuck.  The G5s were the first series to have CPUs with Intel VT.

What you're seeing is the expected result

OK.

So can I even install a 32-bit guest OS?

Yes.  You can do 32 bit VMs.
