Hello,
Did you enable the virtualization in the VM settings ?
If you are using workstation go to VM settings and check the box :
If you are using vSphere :
1. Right-click a virtual machine in the inventory and select Edit Settings.
2. On the Virtual Hardware tab, expand CPU, and select Expose hardware assisted virtualization to the guest OS.
3. Click OK.
