receiving, by VM management software and from a first network device, a request for a universally unique identifier (UUID) of a first VM executing on a first host connected to the first network device;
transmitting, by the VM management software, the UUID directly to the first network device in response to the request;
receiving, by the VM management software and directly from the first network device, a first subscription request to receive configuration change notifications associated with the first VM associated with the UUID;
receiving, by the VM management software and directly from a second network device, a second subscription request to receive the configuration change notifications associated with the first VM associated with the UUID;
receiving, by the VM management software, a migration request to migrate the first VM;
transmitting to the first network device, by the VM management software and based on the migration request, a configuration change notification comprising an indication that the first VM is being migrated; and
initiating, by the VM management software and based on the migration request, a migration of the first VM from the first host to a second host operatively connected to the second network device.
