[Qemu-devel] [Bug 897771] [NEW] qemu 1.0-rc4 no longer able to boot NetBSD-current/i386

[Andreas Gustafsson]

Public bug reported:

Booting a NetBSD-current/i386 install CD using qemu 1.0-rc4 fails. The
same CD does boot in earlier versions of qemu, for example, 0.11.0.

To reproduce, download the

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

and attempt to boot it with:

  qemu -nographic -cdrom boot-com-201111270050Z.iso

This fails with a guest kernel panic:
