# VirtualBox Guset Additionsのログで下記のエラーが出た

``` log:/var/log/VBoxGuestAdditions.log

Creating user for the Guest Additions.
Creating udev rule for the Guest Additions kernel module.
```

## 環境
VirtualBox 5.1.2
ゲストOS: CentOS-6.8-x86_64-minimal.iso を用いて最小構成でinstall

### Guest Additionsをinstallする前に追加で入れたパッケージ

``` bash:
yum install gcc kernel-devel
```

## semanageコマンドはどのパッケージにある?

``` bash:
yum provides /usr/sbin/semanage

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: www.ftp.ne.jp
 * extras: www.ftp.ne.jp
 * updates: www.ftp.ne.jp
policycoreutils-python-2.0.83-29.el6.x86_64 : SELinux policy core python
                                            : utilities
Repo        : base
Matched from:
Filename    : /usr/sbin/semanage
```

## 結論: 更に追加でこれらを入れる

``` bash:
yum install perl policycoreutils-python
```

もちろんGuest Additionを再インストールすること。
