I am trying to install Vsphere 4.0 using VMware Workstation 7.0 on a Delll 670 single core 3.6 GHz hot. I successfully installed VMware Workstation 7.0; however, I could not install the Vsphere 4.0 host within the VMware Workstation. It gave me an error "You hve configured this virtual machine to use a 64 bit operating system. However, 64 bit operation is not possible. This host does not support VT" And then if I go further, I received this error "This version of ESX requires a CPU capable of 64 bit operation"
I know for the fact that the current CPU supports x64 OS because I did successfully installed Wins 7 x64 on the host.
Is there anything I can do to install Vsphere on this host? If not, what is the recommeded hardware I should get to have my goal accomplished?
