在 VirtualBox 4.1.10 软件中安装 openSUSE 12.1 操作系统后，它已经自带了 VBoxGuestAdditions 4.1.4，如下所示：

现在让我们开始安装 VBoxGuestAdditions 4.1.10 吧。
卸载旧版本的 VBoxGuestAdditions首先，使用 zypper 命令卸载 VBoxGuestAdditions 4.1.4：
ben@vbox:~> sudo zypper remove virtualbox-guest-kmp-desktop virtualbox-guest-tools virtualbox-guest-x11 Loading repository data... Reading installed packages... Resolving package dependencies... The following packages are going to be REMOVED: virtualbox-guest-kmp-desktop virtualbox-guest-tools virtualbox-guest-x11 3 packages to remove. After the operation, 6.1 MiB will be freed. Continue?
