The technology disclosed herein enables a data plane of a packet handler in a host to be changed while minimizing disruption to the operation of guests that are associated therewith. In a particular embodiment, the method provides, in a control plane of the packet handler, extracting state information about states of the data plane and pausing network traffic to the data plane. After pausing the network traffic to the data plane, the method provides applying changes to components of the data plane. After applying changes to the components of the data plane, the method provides restoring the states to the data plane using the state information and resuming the network traffic to the data plane.
