Techniques for receiving operational preferences for operating network devices, and determining software updates for the network devices based on the operational preferences. A recommendation system may determine a group of network devices in a device network based on the network devices in the group performing a common functional role or have common attributes. The recommendation engine may further receive the operational preferences for the group of network devices from a user associated with the device network. These operational preferences may be continuously, or periodically, evaluated against actual operating conditions of the group of network devices to determine whether a risk metric associated with the actual operation conditions violates an operational preference. In some instances, the recommendation system may provide the user with access to a recommendation to run updated software that is more optimized for the network device and that satisfies the operational preferences of the user.

Some embodiments provide a method, for configuring logical network entities at a host computer. The method receives configuration data for a particular logical networking entity implemented at the host computer. The method identifies that the configuration data for the particular logical networking entity includes at least two conflicting configuration settings for the particular logical networking entity. At least one of the configuration settings for the particular logical networking entity is based on association of a configuration profile to a group of logical entities that includes the particular logical networking entity. The method determines a particular one of the conflicting configuration settings with a highest priority to apply to the particular logical networking entity at the host computer.

A network control system for managing a plurality of switching elements that implement a plurality of logical datapath sets. The network control system includes first and second controllers for generating requests for modifications to first and second logical datapath sets. The first controller is further for determining whether to make modifications to the first logical datapath set. The second controller is further for determining whether to make modifications to the second logical datapath set. Each controller is further for receiving logical control plane data that specifies logical datapath sets and for converting the logical control plane data to physical control plane data for propagating to the switching elements.
