To determine if Intel VT or AMD-V are enabled in the BIOS:
Log in to the ESX host as the root user. For more information, see Tech Support Mode for Emergency Support (1003677) for ESXi or Unable to connect to an ESX host using Secure Shell (SSH) (1003807) for ESX.
Run this command:
# esxcfg-info|grep "HV Support"
The output of the HV Support command indicates the type of Hyper-visor support available. 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.
