Abstract
Various systems, processes, and products may be used to filter multicast messages in virtual environments. In particular implementations, a system, process, and product for filtering multicast messages in virtual environments may include the ability to, responsive to receiving a multicast message including a destination address, examine a local filtering store of the network adapter for a multicast filtering address matching the destination address. The message is sent to respective virtual machines if the destination address matches the multicast filtering address found in the local filtering store for the respective virtual machines. Responsive to determining that the destination address does not match any multicast filtering address found in the local filtering store, a determination is made whether the local filtering store is full and, if so, the multicast message is dropped.
