That would be IOCTL_PRIVCMD_HYPERCALL_OLD. Is your kernel from the netbsd-4
branch, or netbsd-4-0 ? To use HVM with a newer hypervisor, you need
a kernel from the netbsd-4 branch, and Xen tools built on a system which has
the /usr/include/xen/{xenio,xenio3}.h include files (which the NetBSD 4.0
release doesn't have, but newer builds from the netbsd-4 branch do).
