Running VirtualBox with an existing Windows 7 partition
At work I received a new laptop, and installed linux on it. However, I needed to continue .NET development some of the time, and Visual Studio doesn't play nicely with Wine. So I decided I would run Windows 7 from a virtual machine. This is all well and good, but I didn't want to get another license for it when I already had it installed on the hard drive! While this might be against the terms of the license (I haven't checked), technically the installed Windows 7 copy could only be run as a single instance at any given time. So with some finagling, I was able to get VirtualBox to point to the existing install of Windows 7. There are also purportedly some significant I/O speedups when using VirtualBox directly with a hard drive rather than from a file on the host system.
