Abstract:
1. A method for detecting the operational health of one or more guest operating systems executing within a virtualized operating environment on a managed host computer, the method comprising: exposing, by a out-of-band controller, a first virtual network interface controller to the managed host computer such that the first virtual network interface controller is assigned a network address in an in-band communication channel to allow that the managed host computer communicates with the out-of-band controller through the in-band communication channel via the first virtual network interface controller; bridging the first virtual network interface to a respective second virtual network interface controller exposed to each of the guest operating systems to create one or more bridged network connections; transmitting a command from the out-of-band controller to each of the guest operating systems via the bridged network connections; determining, at the out-of-band controller, if a reply to each transmitted command is received from the guest operating systems; and restoring the operation of each guest operating system from which a reply to the transmitted command is not received.
