Quasar is a mobile computing system built on top of CPU Emulator QEMU. Quasar provides extensive support for migration of computing environments created by QEMU. Quasar is useful for hosting mobile servers and for using the same computing environment at home, in an office, and on a flight. Quasar is equipped with a virtual network mechanism that makes migration transparent to guest operating systems. The mechanism allows network connections to be kept across migration. Quasar also provides a "staged" migration mechanism, which greatly reduces the downtime of servers observed in server migration.
