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.

Abstract translation: 描述了跨虚拟交换机迁移虚拟机（VM）的技术。 要迁移VM，目标分布式虚拟交换机模块可以在迁移之前实例化目标VM主机上的分布式虚拟端口，并为虚拟机的每个虚拟网络适配器预留分布式虚拟端口。 此外，可以将指定为虚拟网络适配器预留的分布式虚拟端口的VM的配置文件从源VM主机复制到目的地VM主机，或者在目的地VM主机中创建。 作为迁移的一部分，虚拟机在源VM主机使用的分布式虚拟端口的网络状态数据将被复制并应用于目标主机上相应的保留的分布式虚拟端口。 然后，当迁移的VM在目标主机上打开电源时，将使用指定保留的分布式虚拟端口的VM配置将VM的虚拟网络适配器附加到预留的分布式虚拟端口。

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.
