Hi,

I'll give this a shot:

These are called by Nova when it plugs and unplugs its network interfaces. Nova drivers are an abstraction layer that allow it to work with different combinations of machine virtualization and switching technologies without knowing the details. Nova makes generic plug and unplug calls and the drivers implement them in a technology specific way. LibvirtOpenVswitchDriver is used by nova-compute for plugging and unplugging LibVirt VMs to Open vSwitch. LinuxOVSInterfaceDriver is used by nova-network for plugging and unplugging the Linux gateway device to Open vSwitch.

Darragh.
