    ESXi not allowing 64bit guests, why?

    Forge64 Novice

      I've got a machine here that was happily running Linux + VMware Server, both 32 and 64bit guests. I previously had ESXi 3.5u4 on it, but the onboard NIC was trouble.

       

      I installed ESXi 4.0 and the SATA required no hackery, and the NIC worked, and I was ecstatic.

       

       

       

      Then I tried adding my VMs back to it via Converter. "Host doesn't support 64 bit guests".

       

       

       

      I figured that had to be a goof, some problem with Converter.

       

       

       

      Set up a new Vista64 guest from scratch, began install, crash "Your computer does not support 64 bit mode". WTF?

      Why would it not be able to run 64bit guests under ESXi 4.0? It ran them under 3.5u4 and under Server 2.0 + Linux host.
