BIOS が使用しているメモリを破壊してしまい BIOS が誤動作している可能性を考えて、特別に予約するなどの対処をせずに VMM がメモリへ書き込む処理を確認しました。 1. 0x255 から 0x25c までに INT 15 の hook 用コードが書き込む {{{ /* 9 bytes hook program */ /* 0000:0255 E7 1F out %ax, $0x1F */ /* 0000:0257 EA ljmp */ /* 0000:0258 XX YY xx yy xxyy:XXYY */ /* 0000:025C CA 02 lret $2 */ }}} 該当の領域は割り込みベクタテーブルのベクタ95h, 96h, 97hのエントリに相当しますが、これらのベクタは使用していないはずなので、問題にはならないと思います。 http://www.ctyme.com/intr/int-95.htm
http://www.ctyme.com/intr/int-96.htm
http://www.ctyme.com/intr/int-97.htm 2. 0x800 から 0xa47 までブートローダをロードするためのコードを書き込む #define GUEST_BOOT_OFFSET 0x800
#define GUEST_BOOT_LENGTH (guest_boot_end - guest_boot_start) 40111fe0 T guest_boot_start
40112228 T guest_boot_end 該当のアドレスは、「guaranteed free for use」のようです。 http://wiki.osdev.org/Memory_Map_(x86)#.22Low.22_memory_.28.3C_1_MiB.29 3. 0x7c00 から 0x7dff までブートセクタをロードする。該当のアドレスは、「RAM - partially unusable (see above) 」ですが、OS BootSector用の場所なので問題なさそうです。 http://wiki.osdev.org/Memory_Map_(x86)#.22Low.22_memory_.28.3C_1_MiB.29

漏れがありました。

4. 0xf000 から 0xf271 まで2個目以降のプロセッサ起動用のコードを書き込む

#define APINIT_OFFSET 0xF000
#define APINIT_SIZE (cpuinit_end - cpuinit_start)
40101097 T cpuinit_start
40101308 T cpuinit_end
「RAM (guaranteed free for use)」なので問題なさそうです。

次の手順で、USBメモリにVMMとGRUBを書き込みました。

# fdisk /dev/sdd

64MBのパーティションを1つ、残りの領域を全て割り当てたパーティションを1つ作成します。「残りの領域を全て割り当てたパーティション」にはブートフラグを付けます。

以下は p コマンドでパーティションテーブルを表示させた結果です。

Disk /dev/sdd: 1006 MB, 1006108672 bytes
31 heads, 62 sectors/track, 1022 cylinders
Units = cylinders of 1922 * 512 = 984064 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x5a2d6305

   Device Boot      Start         End      Blocks   Id  System
/dev/sdd1               1          69       66278   83  Linux
/dev/sdd2   *          70        1022      915833   83  Linux

以下は x コマンドを入力してメニューを切り替えたのち、p コマンドでパーティションテーブルを表示させた結果です。

Disk /dev/sdd: 31 heads, 62 sectors, 1022 cylinders

Nr AF  Hd Sec  Cyl  Hd Sec  Cyl     Start      Size ID
 1 00   1   1    0  30  62   68         62     132556 83
 2 80   0   1   69  30  62 1021     132618    1831666 83
 3 00   0   0    0   0   0    0          0          0 00
 4 00   0   0    0   0   0    0          0          0 00

# mke2fs -j /dev/sdd2
# mount /dev/sdd2 /mnt/tmp1
# grub-install --force --no-floppy --root-directory=/mnt/tmp1/ /dev/sdd2
# vi /mnt/tmp1/boot/grub/grub.cfg

ファイルの中身は次の通りです。

menuentry 'Chain Load' {
        set root='(hd1)'
        chainloader +1
}

# umount /mnt/tmp1

次のコマンドで VMM を USB メモリに書き込みます。

./install_to_usb.sh -f -i 62 -c 'vm0.boot_parttion' /dev/sdd

2回目以降は、-f オプションは不要です。

./install_to_usb.sh -i 62 -c 'vm0.boot_parttion' /dev/sdd

以上の手順で書き込んだUSBメモリをPCに挿入して起動を試みたところ、次のメッセージが出力されて panic しました。

r59 で再現評価をしたところ、panic発生時のRIPが変化しました。

r57 で vm0.boot_int18 を指定しない時に 0x0007 へ jamp してしまうようになっていました。 r60 で修正したところ、panic 発生時の RIP が 0x7c28 に戻りました。
