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.
