This is my fault, I've added VM_GUEST_HV to the guest type enum without
knowing there was another array in a completely different file that
contained a description for those values.
If you (or someone else) are going to commit this change, I would
recommend adding a BIG comment in sys/systm.h above the declaration of
VM_GUEST explaining that if you add a new guest type there you also need
to add a description in subr_param.c, this will probably prevent
something like this happening again.
