Unable to install Windows Server 2008 64 bit edition

[bydemandchd]

I am running ESXi 3.5 on an Intel Core 2 Quad CPU Q8200. When I try and install Windows Server 2008 64 bit edition I get the error that the CPU is not compatible. Could someone please help. Thanks in advance.

You probably need to enable VT-x on your host. Please see .

I take that back. It looks like the Q8200 does not have VT-x. As such, it cannot run 64-bit guests. See KB 1901.
