Abstract
Various innovations for servicing of a virtual switch in a virtual networking layer are presented. The innovations include new architectures for a virtual networking layer and new operations performed when servicing a virtual switch. In some example implementations, during virtual switch servicing, interruption to actual network connectivity is minimal—below a timeout threshold that signifies failure of a network connection. Connections for a host, VMs, and physical network adapter can be maintained while the virtual switch is serviced. Although some interruption to actual network connectivity happens, apparent connectivity (for a VM) over a connection between the VM and the virtual switch can be maintained during the servicing of the virtual switch. Similarly, apparent connectivity (for a host) over a connection between the host and the virtual switch can be maintained during the servicing of the virtual switch.
