Multicast message filtering in virtual environments

Abstract:

Various systems, processes, and products may be used to filter multicast messages in virtual environments. In one implementation, a multicast filtering address is received by a network adapter from at least one of a number of virtual machines of a computer system. Responsive to receiving the multicast filtering address, a determination is made whether a multicast filtering store of the network adapter is full. Responsive to determining that the multicast filtering store of the network adapter is full, the multicast filtering address is stored in a local filtering store of the at least one virtual machine.
