Heh, because kvm_dev_ioctl_create_vm() takes an "unsigned long" for

It's the bit position. We can get only 8 types with u8 actually.
Every architecture defines the meaning, and for x86 we can say it's not
a bit position.
Sorry, I find I was wrong. The types are not bit position but value.
KVM_CAP_VM_TYPES reports the supported vm types using bitmap that bit n
represents type value n.
