>How-To-Repeat:

Get qemu 1.0-rc4 from <http://wiki.qemu.org/Download> and install it
on a host of your choice (not necessarily a NetBSD one).

Then download a NetBSD-current/i386 install ISO from

  
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201111270050Z/i386/installation/cdrom/boot-com.iso

or if that has expired, from

  http://www.gson.org/netbsd/bugs/qemu/boot-com-201111270050Z.iso

and try to boot it:

  qemu-system-i386 -nographic -cdrom boot-com.iso
