[Qemu-devel] FreeBSD booting problem

[Pavel Janík]

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.

pavel@linux:~/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:

pavel@linux:~/.www/tmp.janik.cz/QEMU/FreeBSD> wc -l qemu.log 
324664 qemu.log
pavel@linux:~/.www/tmp.janik.cz/QEMU/FreeBSD> grep -c "add    %al,(%eax)" qemu.log 
299565
pavel@linux:~/.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 ;)
