Described herein are systems and methods for supporting multicast for virtual networks. In some embodiments, a native multicast approach can utilized in which packet replication is performed on a host node of a virtual machine (VM) with a multicast data packet encapsulated in uniquely address unicast packets. In some embodiments, a network virtual appliance can be utilized. A multicast packet sent from the VM can be unicasted to the network virtual appliance. The multicast appliance can then replicate the packet into multiple copies and send the packets to the receivers in the virtual network as unicast data packets encapsulating the multicast packet.

Multi-cast support for a virtual network

Upgrading a non-volatile memory image such as a flash ROM is accomplished by partitioning the flash ROM into a plurality of flash ROM regions. One of the flash ROM regions is selected to receive the software upgrade, which can then be directly overwritten without having to overwrite the flash ROM image in its entirety. Through the use of an image buffer, which stores information about the ROM regions, it is possible to move ROM regions, delete ROM regions, add ROM regions, expand/contact ROM regions, update ROM regions, and enable/disable ROM regions without having to modify the entire ROM image or shadow parts of the ROM image in RAM. Additionally, security and registry information can also be logically linked to a particular region.
