Abstract

A mechanism for managed network filter/forward programming in a virtualization system is disclosed. A method of the invention includes receiving a network programming request from a hypervisor managing a virtual machine (VM), wherein the hypervisor intercepted the network programming request from the VM, determining whether the network programming request satisfies an administrative network policy, and updating network configuration settings as requested by the network programming request if the network programming request satisfies the administrative network policy, wherein the updating occurs without restarting the VM.
