Abstract: The disclosure provides an approach for in-place conversion of a virtual switch on a host. Techniques are provided for in-place conversion of a virtual switch from a first type of virtual switch to a destination type of virtual switch. A method includes rekeying, by a second manager agent, one or more uplink ports associated with one or more logical switches implemented by the virtual on the host with the unique identifier. The rekeying includes updating one or more existing uplink port identifiers assigned to the one or more uplink ports with the unique identifier associated with a first manager agent. The method includes removing, by the first manager agent, an association of the one or more uplink ports with the opaque network; and informing the first manager and the second manager that the virtual switch is of the destination type of virtual switch.

Abstract: Techniques are described for migrating virtual machines (VMs) across virtual switches. To migrate a VM, a destination distributed virtual switch module may, prior to migration, instantiate a distributed virtual port on a destination VM host and reserve the distributed virtual port for each virtual network adapter of the VM. Further, a configuration file for the VM specifying the distributed virtual ports reserved for the virtual network adapters may be copied from a source VM host to the destination VM host or created in the destination VM host. As part of the migration, network state data of the distributed virtual ports used by the VM at the source VM host is copied and applied to the appropriate reserved distributed virtual ports on the destination host. Then, when the migrated VM is powered on at the destination host, the VM configuration specifying the reserved distributed virtual ports is used to attach the virtual network adapters of the VM to the reserved distributed virtual ports.
