If you have been developing Android apps for some time and have been using the default emulator, then you know how frustratingly slow it can be. Even on a powerful machine, it is manageable at best. The emulator is not only slow in booting up, but on all subsequent runs of your app. A solution to this was AndroVM which provided an Android VM client for VirtualBox. This resulted in an emulator that was noticeably faster than the default Android emulator.
