1. A method of migrating a data compute node (DCN) in a datacenter comprising a plurality of host physical computing devices, a compute manager to configure a set of DCNs on the hosts, and a network manager, each host comprising virtualization software, the method comprising:

  • by the compute manager, configuring at least one DCN on each of the plurality of hosts;

    by the network manager, configuring a plurality of logical networks and providing a read-only configuration construct of at least one of the plurality of logical networks to the virtualization software of each host, the read-only configuration construct of each logical network comprising a unique identification of the logical network;

    by the compute manager;

    obtaining, from the virtualization software of a first host, the unique identification of a particular logical network included in the read-only configuration construct of the particular logical network, the particular logical network connected to a DCN configured on the first host;

    determining that the particular logical network is available on a second host based on the unique identification of the particular logical network; and

    configuring the DCN to migrate from the first host to the second host based on the determination that the second host is on the particular logical network.
