VMware Error: CPU does not support long mode Intel Virtualization Technology

Intel Virtualization Technology

If you are running VMware server and have a 64bit system that you are trying to run a 64bit client operating system and you get the following error “CPU does not support long mode” that could mean your bios is not configured correctly. Get into your computers bios and check the cpu settings, there should be a setting for VT (Virtualization Technology) and make sure that is enabled. It is as simple as enabling it, saving the changes and doing a reboot.
