Claim 7:
8. A method for maintaining a persistent network policy for a virtual machine (VM), the method comprising:
receiving, by a first network device, a universally unique identifier (UUID) of a first VM executing on a first host connected to the first network device;
associating, by the first network device, the UUID of the first VM with a network policy for the first VM,
applying, by the first network device, the network policy for the first VM;
subscribing, by the first network device, to receive, directly from VM management software, notifications of changes to a configuration of the first VM corresponding to the UUID, wherein:
the VM management software manages one or more VMs executing on each of a plurality of hosts, including the first VM executing on the first host, and
the VM management software communicates directly with a plurality of network devices including the first network device regarding configurations of the one or more VMs executing on each of the plurality of hosts;

receiving, by the first network device, directly from the VM management software, a configuration change associated with the first VM corresponding to the UUID, wherein the configuration change comprises an indication that the first VM is migrated to a different host; and
removing, by the first network device, the network policy of the first VM based on the configuration change of the first VM.
