VirtualBox 4.x – Failed To Access The USB Subsystem

I’ve just installed VirtualBox on my Linux Mint 11 (Katya) laptop and get the following error when I try to edit the settings on my Ubuntu 11.10 virtual machine:

VirtualBox is not currently allowed to access USB devices. You can change this by adding your user to the ‘vboxusers‘ group. Please see user manual for more detailed explanation.

To add your username to the vboxusers group enter the following command in the terminal (where “your-user-name” is your username on the computer):

sudo usermod -a -G vboxusers your-user-name

All that is left to do after this is reboot your computer.

Thanks to Sebastian for his comment regarding the addition of the -a switch to the usermod command.

Installing Ubuntu 11.4 Natty With Unity-2D in VirtualBox

Unity is the new default interface for Ubuntu as of the 11.4 Natty release. I wanted to take a look at Unity in a virtual machine (to make up my own mind about it) so I fired up VirtualBox on my Windows 7 desktop to take a look.

I already had VirtualBox installed but I made sure that I had the most recent updates installed (currently version 4.0.6).

First download the Ubuntu Natty .iso image and then mount it to a drive letter using Daemon Tools or other similar software. Make a note of the drive letter for later.

Launch VirtualBox and click the New icon and then click Next button to proceed through the Create New Virtual Machine wizard.

Type a Name for your virtual machine and make sure that the OS Type is set to Linux, Ubuntu for the 32 bit version of Ubuntu or Linux, Ubuntu (64 bit) for the x64 version. Click Next.

The wizard defaults to 512MB of RAM for the virtual machine. I elected to up this to 1024MB (i.e. 1GB of RAM). Click Next.

Click Next to create a new virtual hard drive.

Click Next to begin the Create New Virtual Disk Wizard.

Decide whether you want dynamically expanding or fixed size storage (I chose Dynamically expanding storage to save space on my host disk drives). Click Next.

Move the slider (or enter a value) to set the size of your virtual hard disk and then click Next.

Click Finish to complete the wizard.

Before staring the virtual machine click the Settings icon and then Display and set the Video Memory to 32MB (or more) and check the Enable 3D Acceleration check-box. Click OK.

Click the Start icon to begin booting the virtual machine and then click Next on the First Run Wizard.

Select the host drive that has the Ubuntu Natty .iso mounted on it. Click Next.

Click Finish to complete the First Run Wizard.

When this screen appears select your language and then click the Install Ubuntu button.

To update your virtual machine during installation check the Download updates while installing check-box (optional). Click the Forward button.

Click the Forward button to install to the previously created virtual disk with a default partitioning scheme.

Click the Install Now button.

Confirm your time-zone and click the Forward button.

Choose your keyboard layout and click the Forward button.

Enter your Name and Computer Name and Password and click the Forward button.

Enjoy the slide-show of features while Natty installs.

Click Restart Now to reboot your virtual machine.

Un-mount your Natty .iso image and then press Enter in your virtual machine window to continue.

Ubuntu will now reboot – press the Enter key when you see the hardware warning to complete booting into Natty.

I had read here that you should not install Guest Additions to get Unity working – the recommendation was to just install virtualbox-ose-guest-x11 (aka Open Source Guest Additions) and reboot. This did not work for me – so instead I installed Guest Additions along with unity-2d.

To install VirtualBox Guest Additions click the VirtualBox Devices menu and then click Install Guest Additions and follow the prompts.

After that I installed unity-2d (which is available for users who fail to meet the graphical requirements) as follows.

sudo apt-get install unity-2d

I Rebooted one last time and viola!

So I’ll see how Unity works out for me in VirtualBox before deciding whether or not to update my laptop from Lucid. Either way I would anticipate some improvements and polish by the time we get to the next LTS release (which is typically the release than I choose to run).

Ubuntu 10.4 Lucid – Installing VirtualBox

Anyone looking to virtualize guest operating systems on an Ubuntu desktop really can’t go wrong with VirtualBox. For personal use you can either install the Open Source or the more fully featured Full edition. I will be installing the later as it has support for USB and some 3D acceleration (among its many other features).

Installation in Lucid is as follows:

Open the Terminal and edit your /etc/apt/sources.list adding this line:

deb http://download.virtualbox.org/virtualbox/debian lucid contrib

Download and register the public key:

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc 
-O- | sudo apt-key add -

Install VirtualBox:

sudo apt-get update
sudo apt-get install virtualbox-4.0

Click Applications, System Tools and Oracle VM VirtualBox to run the application.

Here you can see VirtualBox running with a Windows 7 virtual machine that I have already installed.
