Abstract
In a data center computing system, multiple nested hypervisors are run, including an outer hypervisor and at least one inner hypervisor running as a virtual machine on top of the outer hypervisor. A guest operating system is run as a virtual machine in the innermost hypervisor. An emulated network interface card device is executed in all hypervisors. An extender component is executed in the outer hypervisor and an extender component is executed in the inner hypervisors such that the extender components in the outer hypervisor and in the inner hypervisors are architecturally cascaded. An interface for the guest operating system is assigned to the emulated network interface card device in each of the outer hypervisor and the inner hypervisors to enable network communications to bypass the outer hypervisor and the inner hypervisors.
