Check if VT-x/AMD-V is Enabled on ESXi Host

Intel’s VT-x and AMD’s AMD-V virtualization features provide functionality which allows for more efficient execution of virtual machines. VMware’s ESXi hypervisor can take advantage of these features if they are enabled in the hosts BIOS. To verify that the host hardware has enabled virtualization features, run esxcfg-info from the ESXi shell and check for the value of HV Support.

~ # esxcfg-info | grep "HV Support"
         |----HV Support............................................3
            |----World Command Line.................................grep HV Support

The table below explains the possible values of HV Support.

0 VT-x / AMD-V support is not available for this hardware.
1 VT-x / AMD-V might be available on this CPU but it is not supported for this hardware.
2 VT-x / AMD-V is available but is currently not enabled in the BIOS.
3 VT-x / AMD-V is enabled in the BIOS and can be used.

If your CPU supports either VT-x or AMD-V but is not enabled and ready for use (3), refer to your hardware documentation for information on how to enable virtualization enxtensions in the system’s BIOS.


Hi All, I like to spend time on black and white screen with linux. I love to learn new things in linux specially in virtualization. Currently I am working on OpenStack like to dig deep.
