Abstract
A non-disruptive, non-migratory hypervisor reboot is performed by suspending execution of the guest operating system, rebooting the container, and then resuming execution of the guest operating system. Suspending execution of the guest operating system can include stopping guest OS access to processing resources. Reboot includes the container loading or reloading itself while preserving the contents of the volatile memory in place. It is also possible to relocate some or all of the contents of the volatile memory to different addresses by creating an abstraction layer.
