h2. Install Virtual Guest Additions
17
18
The VirtualBox Guest Additions for Linux are provided on the same virtual CD-ROM file as the Guest Additions for Windows. They also come with an installation program guiding you through the setup process, although, due to the significant differences between Linux distributions, installation may be slightly more complex than for a windows guest.

Installation generally involves the following steps:

h3. CentOS preperation

Before installing the Guest Additions, you will have to prepare your guest system for building external kernel modules. This works similarly as described in the section called “The VirtualBox kernel module”, except that this step must now be performed in your Linux guest instead of on a Linux host system, as described there. Again, as with Linux hosts, we recommend using DKMS if it is available for the guest system. If it is not installed, use this command for CentOS systems:
25
26
# Install EPEL repository
27
see [[repo_epel|EPEL]]
28
# update everything
29
In order to fully update your guest system, open a terminal and run as root
30
<pre><code class="bash">
31
yum update
32
</code></pre>
33
# Install DKMS
34
Install Dynamic Kernel Module System: (automatically installs appropriate kernel modules per selected version)
35
<pre><code class="bash">
36
yum --enablerepo epel install dkms
37
</code></pre>
38
Be sure to install DKMS before installing the Linux Guest Additions. If DKMS is not available or not installed, the guest kernel modules will need to be recreated manually as root whenever the guest kernel is updated using the command
39
<pre><code class="bash">
40
/etc/init.d/vboxadd setup
41
</code></pre>
42
# install the gcc and kernel development packages
43
Install the GNU C compiler and the kernel development packages using
44
<pre><code class="bash">
45
yum install gcc
46
</code></pre>
47
followed by
48
<pre><code class="bash">
49
yum install kernel-devel
50
</code></pre>
51
# install additional tools
52
Install bzip2
53
<pre><code class="bash">
54
yum install bzip2
55
</code></pre>
56
# reboot
57
Reboot your guest system in order to activate the updates and then proceed as described above.
58
<pre><code class="bash">
59
reboot
60
</code></pre>

h3. installation of Guest Additions via X11
63
64
Insert the VBoxGuestAdditions.iso CD file into your Linux guest's virtual CD-ROM drive. In the "Devices" menu in the virtual machine's menu bar, VirtualBox has a handy menu item named @Install guest additions@, which mounts the Guest Additions .iso file inside your virtual machine.
65
Change to the directory where your CD-ROM drive is mounted and execute as root:
66
<pre><code class="bash">
67
sh ./VBoxLinuxAdditions.run
68
</code></pre>
69
70
Restart the guest.
71
<pre><code class="bash">
72
reboot
73
</code></pre>
74
75
h3. installation of Guest Additions via CLI
76
77
On the host-side stop the guest and then insert the VBoxGuestAdditions.iso CD into the virtual CD-ROM drive via
78
<pre><code class="bash">
79
VBoxManage modifyvm MyCentOSGuest --dvd /usr/share/virtualbox/VBoxGuestAdditions.iso
80
</code></pre>
81
if the CD is not mounted automatically on the guest-side you may do it manually by
82
<pre><code class="bash">
83
mount -t iso9660 -o ro /dev/cdrom /media/
84
</code></pre>
85
<pre><code class="bash">
86
sh /media/VBoxLinuxAdditions.run
87
</code></pre>
88
<pre><code class="bash">
89
umount /media/
90
poweroff
91
</code></pre>
92
93
On the host-side you remove the CD-ROM by
94
<pre><code class="bash">
95
VBoxManage modifyvm MyCentOSGuest --dvd none
96
</code></pre>
