  • Abstract:

    The development of hardware virtualization makes it possible to migrate entire operating system instances across distinct physical machines. Different strategies have been discussed recently, and self migration is one of those impressive ones. By using this solution the OS migration does not need help from the underlying hypervisor. Furthermore the services downtime during the migration can be minimized. Nevertheless self migration has it own shortcomings.

    With the help of pre-virtualization technique, we try to keep all advantages of self migration and overcome its main drawback by using a new migration technique, "In Place Migration", in this thesis. We introduce firstly pre-virtualization, compare it with other classical hardware virtualization, show its strength, and then discuss how we use the new concept of "In Place Virtual Machine Monitor"(In Place VMM) from pre-virtualization to design and implement "In Place Migration".
