Determining if Intel Virtualization Technology or AMD Virtualization is enabled in the BIOS without rebooting

Taken from Vmware KB “Determining if Intel Virtualization Technology or AMD Virtualization is enabled in the BIOS without rebooting” (29 Jul 2010)

Purpose
When troubleshooting VMotion, Enhanced VMotion Capability (EVC) or 64bit virtual machine performance, you may need to determine if the Intel Virtualization Technology (VT) or AMD Virtualization (AMD-V) are enabled in the BIOS.

Resolution

1. Login to the ESX host as the root user.

2. Run this command

# esxcfg-info|grep "HV Support"

These are the descriptions for the possible values:

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