Find out if Intel-VT or AMD-V enabled in the BIOS without rebooting


How-to findout without reboot if the Intel VT or AMD-V are enabled in the BIOS.

When you working with VMotion, Enhanced VMotion Capability (EVC), or 64bit virtual machine performance, you must make sure if Intel Virtualization Technology (VT) or AMD Virtualization (AMD-V) are enabled in the BIOS.

This article provides a method to determine if Intel VT or AMD-V are enabled in the BIOS without rebooting.

1. Log in as root to the ESX Service Console.

2. Run the command:

# esxcfg-info|grep HV

The output indicates if can be interpreted as follows:

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