The VM is configured for 64bit guest os. However,64bit operation is not possible. Long mode is disabled for this Vm


Symptoms:

 

Unable to power on a 64bit virtual machine.

 

The CPU is Virtual Technology-capable, but Virtualization Technology (VT) is not enabled.

 

Unable to install a 64bit operating system.

 

The virtual machine has been migrated and it no longer powers on.

 

You see one of these errors when trying to vMotion to a host that does not have VT enabled:

 

The CPU of the host is incompatible with the CPU feature requirements of virtual machine.

 

The CPU of the host is incompatible with the CPU feature requirements of the virtual machine; problem detected at CPUID level 0x80000001 register ‘edx’

Resolution:

Ensure that your processor supports EM64T and VT.

All Intel Xeon processors feature:

Intel Virtualization Technology

Intel Extended Memory 64 Technology

Execute Disable Bit

 VT must be enabled in the host system BIOS. The feature may be named VT, Vanderpool Technology, Virtualization Technology, VMX, or Virtual Machine Extensions. Often, you find this setting under a Security screen in the BIOS. The location of this setting may change depending on the system vendor.
