-===== VirtualBox tips/tricks ===== +===== VirtualBox ===== 
- +VirtualBox is free/opensource Hypervisor from Sun Microsystems.  It has performance on par with VMware and is very mature.  We have two virtualization servers, [[biovbox]] and biovboxtesting.
-==== Commonly-used commands ==== +
-To change between "not attached", NAT,Bridged,internal network and host olny adapter:  +
-<code>VBoxManage modifyvm <uuid|name> [--nic<1-N> none|null|nat|bridged|intnet|hostonly]</code> +
-Set the boot order: +
-<code>VBoxManage modifyvm <uuid|name> [--boot<1-4> none|floppy|dvd|disk|net>]</code> +
-Add shared folder: +
-<code>VBoxManage sharedfolder add <vmname>|<uuid> --name <name> --hostpath <hostpath> [--transient] [--readonly] </code> +
-Acpi Vm: +
-<code>VBoxManage controlvm  <uuid>|<name>pause|resume|reset|poweroff|savestate|acpipowerbutton|acpisleepbutton| </code> +
-Change rdp address: +
-<code>VBoxManage modifyvm <uuid|name> [--vrdpaddress <host>]</code> +
-Change the Authentication type:  +
-<code>VBoxManage modifyvm <uuid|name> [--vrdpauthtype null|external|guest]</code> +
-**Note**: option "external" will limit access to individual users, The user will be required to use rdesktop-vrdp with username and password: +
-<code>rdesktop-vrdp -u <username> -p - <host ip address>:<vrdp port></code> +
-Change rdp port: +
-<code>VBoxManage modifyvm <uuid|name> [--vrdpport <port>]</code> +
-List all VMs in the server: +
-<code>VBoxManage list vms</code> +
-List all running VMs: +
-<code>VBoxManage list runningvms </code> +
- +
-PORT FORWARDING!! +
-<code>$ VBoxManage setextradata b3924a0c-70a1-4890-8dff-3cc308cdaf28 "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort" 2223 +

 +===== Networking ===== 
 +==== Bridged Networking ==== 
 +If your guest is using bridged networking you MUST use this command to allow other users to use the host's physical network card.  Make sure your virtual machine is shut down and then run this command: 
 +<code>VBoxManage setextradata MyMachine VBoxInternal/Devices/pcnet/0/LUN#0/Config/RestrictAccess 0</code> 
 +Each and every VM using bridged networking must use this command.  If you are seeing errors like ''VERR_PERMISSION_DENIED'' regarding the network interface, this is the cause! 
 + 
 +As of VirtualBox 3.1.2 this is still a [[http://www.virtualbox.org/ticket/2852|known issue]]. 
 ==== Port Forwarding ==== ==== Port Forwarding ====
  
-If your guest OS is using NAT for networking you will need to enable port forwarding.  There is no GUI for this in VirtualBox, but you can use ''VBoxManage setextradata'' to make the required changes.  If you want to SSH to your VM, for example:+If your guest OS is using NAT for networking and you want to access services like Apache or SSH, you will need to enable port forwarding.  There is no GUI for this in VirtualBox, but you can use ''VBoxManage setextradata'' to make the required changes.  If you want to SSH to your VM, for example:
 <code>$ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort" 2223 <code>$ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort" 2223
 $ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/GuestPort" 22 $ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/GuestPort" 22
-$ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/Protocol" TCP+$ VBoxManage setextradata Ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/Protocol" TCP</code>
 Then you can log in to the VM from your own computer using the port you've forwarded above: Then you can log in to the VM from your own computer using the port you've forwarded above:
-<code>$ ssh -p 2223 username@172.26.0.205</code>+<code>$ ssh -p 2223 username@172.26.0.200</code> 
 +===== Updating VirtualBox ===== 
 +To update VirtualBox to a new version you must shutdown all the running VMs.  You can do this by first looking to see which VMs are running (''ps auxw | grep VBox'') and then shutting down or saving the state of each one.
