ESXi Guest OS (VMWareworkstation pro over Win 2K12 R2)Popping an Error: This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible. This host does not support Intel VT-x.

Hello Friends,

Host Machine Configuration:

Cisco UCS C220M4

2 Intel Xeons (10 Core)

128 Gb Memory (16Gb * 4)

ESXi 6.5 (Essentials License)

Guest OS:

Windows Server 2012 R2 (Installed with VMWare Workstation Pro 12)

GNS3 VM OVA is sucessfully imported to VMWare Workstation But when i am trying to power on the GNS3 VM it is popping me this error "This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.  This host does not support Intel VT-x."

I Checked the Guest OS settings at ESXi and as well as VMWare Workstation Pro. I found that both are enabled with Intel VT-X

Is n't it allowed, running a Hypervisor over Guest OS.

Please help me
