A remote management controller is provided for use in conjunction with a managed host computer. The remote management controller exposes a virtual network interface controller, such as a driverless virtual USB network interface controller, to the managed host computer. Through the in-band connection provided by the virtual network interface controller, the remote management controller can send a command to the host operating system or one or more guest operating systems executing in a virtualized environment. If no reply is received to the command, the remote management controller takes corrective action to restore the operation of the host operating system or the non-responsive guest operating systems.
