I tried to boot Haiku on Qemu 0.14.1 on Ubuntu 11.10. "disable local apic" is required to boot.
qemu -hda ./haiku.image -m 1024 -usb -usbdevice mouse -serial stdio -net user -net nic
qemu: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"

Doing tests, I noticed init_sse was called twice in spite of the system being monoprocessor in arch_smp_init_percpu() and arch_cpu_init_post_vm(). Fixing this gets us a bit farther.
