    Abstract: Embodiments described herein involve appliance migration. Embodiments include connecting, by a second appliance that is configured to perform a service, to a first uplink and a first downlink of a first appliance that is configured to perform the service. Embodiments include connecting, by the second appliance, to a first endpoint and a second endpoint to which the first appliance is connected. Embodiments include determining, by the second appliance, existing flows processed by the first appliance. Embodiments include processing, by the second appliance, a plurality of packets received via the first endpoint by: forwarding, by the second appliance, first packets of the plurality of packets that correspond to the existing flows to the first appliance; and performing, by the second appliance, the service for second packets of the plurality of packets that do not correspond to the existing flows.

    Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node. In such embodiments, the service forwarding plane does not have a port that directly receives data messages from, or supplies data messages to, any guest machine. Instead, in some such embodiments, data associated with a guest machine is routed to a port proxy module executing on the same host computer, and this other module has a service plane port. This port proxy module in some embodiments indirectly can connect more than one guest machine on the same host to the service plane (i.e., can serve as the port proxy module for more than one guest machine on the same host).

    Abstract: Some embodiments provide a method for managing multiple queues of a network interface card (NIC) of a host computer that executes a data compute node (DCN). The method defines first, second, and third subsets of the queues. The first subset of queues is associated with a first feature for processing data messages received by the NIC, the second subset of queues is associated with a second feature, and the third subset is associated with both features. The method receives a request from the DCN to process data messages addressed to the DCN using both the first and second features. The method configures the NIC to direct data messages received for the DCN to a queue that is selected from the third subset of queues.

    Abstract: Some embodiments of the invention provide a method of upgrading a firewall module executing on a host computer to process traffic sent to and from machines executing on the host computer. While a first version of the firewall module executes on the host computer to process the traffic to and from the machines, the method loads a second version of the firewall module alongside the first version of the firewall module. For each of multiple ports associated with machines executing on the host computer for which the firewall module processes traffic sent to and from the port, the method saves a runtime state of the first version that relates to the port, transfers association of a firewall filter associated with the port from the first version to the second version, and restores the saved runtime state for the port to the second version.

    Abstract: A method for managing several queues of a network interface card (NIC) of a computer. The method initially configures the NIC to direct data messages received for a data compute node (DCN) executing on the computer to a default first NIC queue. When the DCN requests data messages addressed to the particular DCN to be processed with a first feature for load balancing data messages across multiple queues and a second feature for aggregating multiple related data messages into a single data message, the method configures the NIC to direct subsequent data messages received for the DCN to a second queue in a first subset of queues associated with the first feature if a load on the default first queue exceeds a first threshold. Otherwise, if a load on the first subset of queues exceeds a second threshold, the method configures the NIC to direct subsequent data messages received for the particular DCN to a third queue in a second subset of queues associated with both the first and second features.
