A method, a system, and computer readable program code for managing cache coherence in a virtual machine managed system are provided. In response to a processor issuing a message to be broadcast, a determination is made as to whether the processor is part of a virtual domain. In response to a determination that the processor is part of the virtual domain, the message and a first bit mask are sent from a source node to a destination node. In response to receiving the message and the first bit mask, one of a primary link or a secondary link is selected to send the message and the first bit mask over, forming a selected link. The message and the first bit mask are sent to the destination node over the selected link.
