VirtualBox: 64-bit Guest OS

VirtualBox and Hyper-V

While playing with Vagrant, VirtualBox, and MongoDB on my old ASUS ROG Generation 1 - which has Intel Q720 CPU and runs Windows 10 64-bit - I ran into this error.

VT-x is not available(VERR_VMX_NO_VMX).
VirtualBox error: Intel VT-x is not available

Also, VirtualBox list only 32-bit version for guest OS.

It is so weird because I can installed Ubuntu 64-bit as guest OS in VirtualBox while booting this laptop in Windows 7 64-bit.


I tried removing Hyper-V feature and reboot.


VirtualBox now display 64-bit version of guest OSes.


And Vagrant works too.
