VT-x is not available (VERR_VMX_NO_VMX).

There is a bug in VirtualBox, it is already documented and recorded under Ticket #18387.

It has to do with Vbox failing to properly detect and use Hyper-V under Win10.

There is a longer discussion and some possible solutions discussed on the VirtualBox forum https://forums.virtualbox.org/viewtopic.php?f=6&t=90853

One solution is to open command prompt as administrator and run

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

After that reboot try VirtualBox again.

thanks Tiron, i had been testing some labs for azure which had been relying on hyper v then finding all my other Vbox labs not functioning.
