[meta-virtualization] MinnowBoard Max Hardware Virtualization

Hello,

I compiled the latest version of yocto with meta-virtualization layer for
Minnowboard Max.

MbMax have hardware virtualization support,

grep vmx /cpu/procinfo shows the vmx flags.

But when I boot the board, dmesg|grep kvm shows "kvm: no hardware support".

I do see kvm loaded as module. Is there some other settings that I need to
switch on, so that kvm understands that the hardware has the correct
virtualization support.

Or could it be just the UEFI thats disabling it?

modinfo kvm-intel gives the following output
