+ VM networking related points in addition to before/after vm
start/stop
before_hotplug_nic(conf={}, customProperty={})
*after_hotplug_nic(conf={}, customProperty={})
before_hotunplug_nic(conf={}, customProperty={})
*after_hotunplug_nic(conf={}, customProperty={})
* Not sure about use case for those two
Yep, part of them already proposed by Itzik (look at [1])
The above will require VM IDs and networks? Sorry that I did not
look
into the actual implementation of the above naming is more of a
guess work, but I think the meaning is clear. There may be other VM
networking related entry points I've missed.
