==Installation==

=== RedHat ===

Download VirtualBox RPM (I am using the RHEL5 RPM)
# Download: VirtualBox-1.5.6_28266_rhel5-1.i586.rpm

Install dependencies:
# i386
#yum install gcc kernel-devel libSDL-1.2.so.0 libasound.so.2 libqt-mt.so.3 libxslt.so.1
yum install gcc kernel-devel SDL alsa-lib qt libxslt

# x86_64
yum install gcc kernel-devel SDL.x86_64 alsa-lib.x86_64 qt.x86_64 libxslt.x86_64

Install RPM:
# i386
rpm -Uvh VirtualBox-1.5.6_28266_rhel5-1.i586.rpm

# x86_64
rpm -Uvh VirtualBox-1.6.0_30421_rhel5-1.x86_64.rpm

=== Ubuntu ===

apt-get update ; apt-get install virtualbox

=== Kernel Module ===

These installs will attempt to compile the kernel module. If you need to rerun the setup due to a failure, run:
/etc/init.d/vboxdrv setup

VBox_vs_Others – Oracle VM VirtualBox - VirtualBox vs. VMware vs. Parallels - http://www.virtualbox.de/wiki/VBox_vs_Others

== GUI ==

The VirtualBox GUI can create and control VMs

==Command Line Tools==
VBoxManage is our command-line interface (See chapter 7 of the [http://www.virtualbox.org/download/UserManual.pdf user manual])

List VMs:
VBoxManage list vms

Show VM details:
vm showvminfo <name>

Start VM:
VBoxManage startvm <name>

# Start with RDP support
VBoxManage startvm <vmname> -type vrdp
VBoxHeadless -startvm <vmname>
VBoxHeadless -startvm <vmname> -p <port>
#VBoxVRDP has been renamed VBoxHeadless in v1.6

Stop VM:
VBoxManage controlvm <name> poweroff

Reset VM:
VBoxManage controlvm <name> reset

Add aliases for easy usage:
vi /etc/bashrc
alias vm=VBoxManage
alias vmlist="vm list vms | grep Name"

==Creating a virtual machine on a headless server==
[http://www.virtualbox.org/download/UserManual.pdf VirtualBox User Manual 7.4.2 Step by step: creating a virtual machine on a headless server]:

Set virtualbox name:
VBOXNAME="centos5"

Create Virtual Machine:
VBoxManage createvm -name "$VBOXNAME" -register

Settings for VM:
VBoxManage modifyvm "$VBOXNAME" -memory "256MB" -acpi on -boot1 dvd -nic1 nat

Create virtual disk (10GB):
VBoxManage createvdi -filename "$VBOXNAME.vdi" -size 10000 -register
VBoxManage modifyvm "$VBOXNAME" -hda "$VBOXNAME.vdi"

Attach ISO to VM:
VBoxManage modifyvm "$VBOXNAME" -dvd /full/path/to/iso.iso
# VBoxManage modifyvm "$VBOXNAME" -dvd ~/CentOS-5.1-i386-bin-1of6.iso

Start VM RDP:
VBoxVRDP -startvm "$VBOXNAME"

Connect via RDP to VM:
rdesktop -a 16 my.host.address

Unmount ISO so reboots work:
VBoxManage modifyvm "$VBOXNAME" -dvd none

==Bridge Networking==
Install bridge tools:
yum install bridge-tools

Setup a bridge network:
# create bridge
brctl addbr br0

# remove address from eth0 (will disable networking)
ifconfig eth0 0.0.0.0

# add interface to bridge
brctl addif br0 eth0

# reconnect network
dhclient eth0
or...
ifconfig br0 x.x.x.x netmask x.x.x.x

# create permenant virtual interface
VBoxAddIF vbox0 root br0

# delete virtual interface
VBoxDelIF vbox0

# list current virtual interfaces
ifconfig

For a permenet bridge configuration:
# Add bridge device
# /etc/sysconfig/network-scripts/ifcfg-br0
<s>DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
ONBOOT=yes</s>

# the bridge will take over eth0, so set it to the static IP of eth0
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
IPADDR=10.161.101.6
NETMASK=255.255.255.0
ONBOOT=yes

# Add eth0 to bridge
# /etc/sysconfig/network-scripts/ifcfg-eth0
BRIDGE=br0

# Restart service
/sbin/service network restart

# Create virtualbox host interface and add to bridge
# vbox0 => "all host interfaces created in this way must be called vbox followed by a number"
# <user> => "Replace <user> with the name of the user who is supposed to be able to use the new interface."
# To see current host interfaces see ifconfig
VBoxAddIF vbox0 <user> br0

# Delete if needed...
VBoxDelIF vbox0

# Tell VM to use virtual interface under "settings"->"network"->"attached to"
# and enter "vbox0" into the "interface name" field.

# NOTE: A VIRTUAL INTERFACE CAN ONLY BE USED WITH WITH ONE VIRTUAL MACHINE

Switch VM interface to host interface mode:
VBoxManage modifyvm "$VBOXNAME" -hostifdev1 vbox0
#VBoxManage modifyvm "$VBOXNAME" -nic1 hostif
