Ubuntu 12.10 – VirtualBox Guest Additions not Working
This applies to Ubuntu 12.10 running under VirtualBox version 4.1.22 (or earlier), 4.2.0, 4.2.2, and 4.2.4 under Windows 7 with Service Pack 1. The issue and solution is likely the same for all versions of VirtualBox 4.1.22 and 4.2.x, regardless of which OS they are running on. Unfortunately, the problem with VirtualBox 4.2.2, and 4.2.4 has no solution at the moment. This problem is resolved in VirtualBox 4.2.6 and later. Note: you will need to reinstall the VirtualBox Guest Additions.

VirtualBox – How to Access USB Devices
These instructions are for VirtualBox 4.1.18 running on Windows 7 with Service Pack 1 with Ubuntu 12.04 (running the Unity Interface) as the guest OS. I believe the instructions are the same (or very similar) regardless of which host OS and guest OS combination you are running, but I make no guarantee. Sometimes you want to (or need to) directly access a USB device, like a memory stick, or a printer, or camera. Normally, VirtualBox does not provide access to these devices, however, it is possible to allow the guest OS to directly access the USB device. (I needed to allow Linux to directly access a SD card so I could use the dd command to copy a OS image. This turned out to be very slow. I am not sure if this was … Read entire article »

Ubuntu 12.04 – Virtualbox Guest Additions Stop Working after Update
These instructions are for Ubuntu 12.04, with the Unity interface, running under VirtualBox 4.1.12_77218. They should be the same or similar for other version combinations, but no guarantee is made. Sometimes, when Ubuntu updates are applied to your system, the VirtualBox Guest Additions stop working. Symptoms may include: (1) screen resolution reverts back to the default setting, (2) shared folders no longer work. Trying to fix it by selecting Install Guest Additions… does nothing (and it won’t because Guest Additions are already installed). The fix is to rerun the Guest Additions installation program. There are three ways to do this. Method 1 I think this is the easiest and fastest way. 1) Locate the VBOXADDITIONS disk icon (it is probably the only disk icon) located near the bottom of the Launcher (it is most likely just … Read entire article »
