This is a simple test case that runs an image with kvmtool and
kvm-unit-tests which can validate virtualisation works. This is useful
for exercising TCG but can also be applied to any nested virt setup
which is why it doesn't specify an accelerator.
You might want to update this text give now...

You are now forcing tcg. Or are you planning on adding additional tests
bellow to exercise split and KVM (when we have nested support for
HVF/KVM)?
I don't know about KVM. For HVF/split I'm using:
