Maybe a silly question, but how do I enable CONFIG_HYPERVISOR_GUEST with
this config.

I run:
ARCH=arm64 CROSS_TOOLCHAIN=aarch64-unknown-linux- make menuconfig
and search for HYPERVISOR_GUEST, it reads:

Symbol: HYPERVISOR_GUEST [=HYPERVISOR_GUEST]
Type  : unknown

With no option to go to or select it.
