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.
