Qemu and Ubuntu 8.04.3 with a shared folder
In the following tutorial we show you how to use Qemu to run Ubuntu 8.04.3 from a flash drive, within Windows without rebooting. In addition, you will be able to mount the shared folder on the flash drive and use it between Windows and Ubuntu to share files between the two operating systems. Please note that you should only access the files in the shared folder with one operating system at a time. The running Ubuntu 8.04.3 OS will function like the Live CD. The persistence option is not being utilized.
The advantage to using Qemu hardware emulation as opposed to a native USB boot or CD boot is that you can to plug your USB stick or portable hard drive into any available Windows PC and run a completely separate Linux operating system without rebooting the Windows Host PC. In addition you can save specific work done in Linux to the shared folder and have access to this folder from Windows.
