Hi,
people on IRC channel reported problems booting FreeBSD ISO images and
floppies. I have tried booting this floppy image:
http://tmp.janik.cz/QEMU/FreeBSD/boot.flp
with current CVS as of now.
address@hidden:~/Tmp/QEMU> /tmp/QEMU/bin/qemu -pci -boot a -fda
~/.www/tmp.janik.cz/QEMU/FreeBSD/boot.flp -S
Serial port redirected to /dev/pts/143
QEMU 0.5.5 monitor - type 'help' for more information
(qemu) log in_asm
(qemu) c
(qemu)
and /tmp/qemu.log contains:
...
IN:
0x000090d6: xor %ecx,%ecx
0x000090d8: mov %ecx,%cr3
----------------
IN:
0x000090db: lgdtl 0x96d0
0x000090e2: ljmpw $0x18,$0x90e8
Full log is available at
http://tmp.janik.cz/QEMU/FreeBSD/qemu.log.bz2
Interesting thing is:
address@hidden:~/.www/tmp.janik.cz/QEMU/FreeBSD> wc -l qemu.log
324664 qemu.log
address@hidden:~/.www/tmp.janik.cz/QEMU/FreeBSD> grep -c "add %al,(%eax)"
qemu.log
299565
address@hidden:~/.www/tmp.janik.cz/QEMU/FreeBSD>
Ie. 93% of all executed instructions is
add %al,(%eax)

Ask three people which VM is best, and you will get four answers ;)
