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

A DHCP server implementation includes transmission of a DHCP packet from a virtual machine executing on a server node to a node agent executing on the server node, generation, by the node agent, of a DHCP response packet based on the DHCP packet and on DHCP information previously stored in a local memory of the server node, and transmission of the DHCP response packet from the node agent to the virtual machine. Neither the DHCP packet transmitted by the virtual machine nor the DHCP response packet are transmitted out of the server node.
