Abstract
Some embodiments provide a network system that includes several host machines for hosting virtual machines, divided into several different domains. The network system includes several local domain management servers. A first local domain management server of a first domain is for (i) initiating creation of a set of distributed virtual switch ports associated with a particular logical network identifier on a host machine within its domain and (ii) attaching a first virtual machine on the host machine to a created port associated with the particular logical network identifier in order for the first virtual machine to send traffic over the logical network. The network system includes a second level management server for coordinating the use of logical network identifiers between multiple different logical domain management servers in order for the first virtual machine to communicate via the logical network with a second virtual machine in a second domain.
