This host is VT-capable, but VT is disabled


While starting VM on 64 bit, got following error -

This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.

This host is VT-capable, but VT is disabled.

VT might be disabled if it has been disabled in the BIOS settings or the host has not been power-cycled since changing this setting.

(1) Verify that the BIOS settings enable VT and disable 'trusted execution.'

(2) Power-cycle the host if either of these BIOS settings have been changed.

(3) Power-cycle the host if you have not done so since installing VMware Player.

(4) Update the host's BIOS to the latest version.

For more detailed information, see http://vmware.com/info?id=152.

Continue without 64-bit support?

Resoulution -


We are still trying to determine what causes this problem on some systems.  In the meantime, as a workaround, please add the following line to C:\ProgramData\VMware\VMware Workstation\config.ini:

hv.assumeEnabled = TRUE

Note that ProgramData is a hidden folder.

new error - 


*** VMware Player internal monitor error ***

vcpu-0:VT is disabled and locked on this CPU.

Solution -


Go to BIOS setup- 
- Restore CMOS factory default setting
- Make sure to enable Virtulization Technology
- Cold boot the system

Issue solved ... :)
