Installing esxi 5.1 on a virtual machine on esxi 5.1, getting "VMWare requires the Execute Disable/No Execute CPU feature to be enabled"

Hi,

I am trying to install a ESXi server on a virtual machine in a vSphere 5.1 environment, but keep getting the purple screen with "VMWare requires the Execute Disable/No Execute CPU feature to be enabled" notification.

I have set guest OS to ESXi 5.x and CPU/MMU virtualization to Intel VT-x/AMD-v (tried both for MMU and EPT/RVI options).

Any ideas would be greatly appreciated.

Thanks!

Eli

Hi,

Thanks for your response!

I have this checkbox grayed out, does this mean that I am unable to run nested ESXi on this server?

BTW It's esxi 5.0, not 5.1

Kind regards,

Ilya Nikolaev

Hi Ilya,

If that box is greyed out, this means that virtualization support may not be present. You can confirm by running the CPU utility

If your Desktop support Intel-VT or AMD-VT feature enable that feature logging into BIOS and you required 64Bit compatible CPU and 2 GB memory for ESXi 4.1 or ESXi 5.1, try with vmware workstation 9.0 or in .vmx file you need add one line.
