Enable VT-x switch for HOST

[GaryGhotra]

I am running Ubuntu 12.04 Desktop 64Bit LTS guest in my ESXi 4.1 as my development environment. For some reason, I would like to create virtual machines inside it to run some emulators but seems like VT-x is not enabled and tried every possible way without any success.

I have tried to get into BIOS but there is no option to switch ON/OFF like you find one in machine BIOS.

Secondly I have tried to directly switch on KVM as it is mentioned in VM settings virtualization that it depends on your guest OS.

# sudo apt-get -y install qemu-kvm

# sudo modprobe kvm-intel

FATAL: Error inserting kvm_intel (/lib/modules/3.2.0-51-generic/kernel/arch/x86/kvm/kvm-intel.ko): Operation not supported

Thank you for any help

ESX 4.1 does not virtualize VT-x.  ESX 5.0 does, but the feature is unsupported.  The first release of ESX to support virtualization of VT-x is ESX 5.1.
