Abstract: A system can allow a user to continue using a virtual machine while a background reboot occurs on a clone of the virtual machine. A backup agent operating on a server can receive a request from a virtual machine operating in an active state, to complete a reboot operation without operational interruption. A hypervisor can clone the virtual machine. During and after cloning, the backup agent can cause a filter agent to capture changes to the virtual machine. The virtual machine clone can notify the backup agent that the reboot is complete. Changes made in the interim on the virtual machine can be integrated on the virtual machine clone. Then the hypervisor can transition usage from the virtual machine to the virtual machine clone.

Abstract: A method of rebooting a computing system in which a virtual machine (VM) runs on top of a hypervisor and a host operating system (OS) includes the following steps. Those steps are sending, from the host OS to the hypervisor, a pre-reboot notification that the host OS is going to reboot, in response to reception of the pre-reboot notification, saving by the hypervisor state of a session that is executing in the VM, rebooting the host OS, after the host OS is rebooted, logging on to the host OS using a credential provider that was previously registered with the host OS and sending a post-reboot notification from the host OS to the hypervisor, and in response to reception of the post-reboot notification, instantiating by the hypervisor a VM in which the session is resumed using the saved state of the session.
