Abstract: A method for a primary virtual machine (VM) to schedule a sibling VM task executed by a hypervisor. Upon request of the sibling VM, the hypervisor creates a sibling task which includes a hypervisor ID. The hypervisor ID is then communicated to the primary VM. Subsequently, the primary VM creates a broker task, identified by its broker ID, and based on the received hypervisor ID for the sibling VM task. The primary VM then communicates to the hypervisor a mapping of the broker ID to the corresponding hypervisor ID. Finally, the primary VM executes the broker task when instructed by a scheduler of the primary VM. The broker task then triggers the hypervisor to run the corresponding sibling task based on the mapping.
