いきさつ

Linux のカーネル系を一気に update しまくったら、VirtualBox の共有フォルダがマウントできなくなった。
どうもカーネルモジュールを更新した場合、Guest Additions を再度インストールする必要があるみたい。

なので、Guest Additions をインストール。

[root@centos ~]# mount -r /dev/cdrom /mnt/cdrom
[root@centos ~]# /mnt/cdrom/VBoxLinuxAdditions.run 
Verifying archive integrity... All good.

あれ？

エラーが発生してる？？
前はちゃんとインストールできてたのに？

ログを調べてみると

/var/log/vboxadd-install.log

/tmp/vbox.0/r0drv/linux/memobj-r0drv-linux.c:1542:26: error: 'struct mm_struct' has no member named 'numa_next_reset'
pTask->mm->numa_next_reset = jiffies + 0x7fffffffffffffffUL;

なんじゃこりゃ。。。

VirtualBox 4.3.12 のバグっぽいらしく、問題報告はあがっているとのこと。
けど、インストールできないと仕事に影響でてしまう。

対策

パッチを適用して流してやるしかないっぽい。
参考サイトを見ながらシェルを作成。

vboxbuild

set -e
mount -r /dev/cdrom /mnt/cdrom
sh /mnt/cdrom/VBoxLinuxAdditions.run --noexec --keep
umount /mnt/cdrom

# Apply patch
cur_dir=$(pwd)
tmp_dir=$(mktemp -d)
patch=VBox-numa_no_reset.diff

あとは、Guest Additions CD Image をセットしておき、

[root@centos mnt]# sh /mnt/vboxbuild

で実行してやれば、

見事にインストール成功しました。
※CUIで運用しているので OpenGL はエラー出てます。

助かりました。
感謝！
