Error log? What is the command? pkgin install?

KVM-style?

NetBSD does support HAXM (--accel hax) and in a downstream copy NVMM
(-accel nvmm).

http://blog.netbsd.org/tnf/entry/the_hardware_assisted_virtualization_challenge

http://blog.netbsd.org/tnf/entry/from_zero_to_nvmm

Once NVMM will stabilize we intend to submit it upstream.

There is no support for hardware assisted acceleration in qemu for any
other BSD.
