Abstract: Example methods are provided for a host to perform packet processing using a service chain in a software-defined networking (SDN) environment. The method may comprise establishing a datapath between a first virtualized computing instance and a second virtualized computing instance in the service chain, the datapath bypassing a forwarding element to which the first virtualized computing instance and the second virtualized computing instance are connected. The method may also comprise: the first virtualized computing instance obtaining a packet that requires processing by the service chain, and performing packet processing according to a first service. The method may further comprise: the second virtualized computing instance obtaining the processed packet via the datapath, and performing packet processing according to a second service.

Abstract: Example methods are provided for configuration tracking in a virtualized computing environment. One example method may comprise detecting a configuration request to configure a physical component, or a virtual component, of a host; identifying a particular interface via which the configuration request is initiated by a client device; and identifying one or more attributes associated with the configuration request. The particular interface may be one of multiple interfaces supported by the host or the management entity, or both. The method may also comprise generating configuration history information specifying the particular interface and the one or more attributes associated with the configuration request.

Abstract: A virtual machine (VM) system includes a network, hosts that are able to communicate over the network, a storage cluster of nodes made up by the hosts, and VMs running on the hosts. As part of the storage cluster, the nodes pool their storage devices into a clustered datastore shared across all the nodes. The VMs are stored in the clustered datastore. Two of the nodes take roles of a reflector node and a backup reflector node. The other nodes, excluding the reflector node but including the backup reflector node, are configured to establish unicast connections over the network with the reflector node. The nodes in the storage cluster are configured to communicate clustering service information over the unicast connections.

Abstract: An example method is provided for a network device to protect a Media Access Control (MAC) address table of a network switch in a virtualized computing environment. The method may comprise, in response to receiving a request message from a virtual machine, determining a shared MAC address that is usable for the virtual machine and at least one other virtual machine, modifying a source MAC address of the request message from a MAC address associated with the virtual machine to the shared MAC address; and sending, to the network switch, the request message having the shared MAC address as the modified source MAC address. The method may comprise, in response to receiving a reply message from the network switch, the reply message having the shared MAC address as a destination MAC address, sending, to the virtual machine, the reply message in reply to the request message.
