Subject: [Engine-devel] Network related hooks in vdsm
Hi everyone,
As you know vdsm has hooks mechanism and we already support dozen of
hooks for different needs.
Now it's a network's time.
We would like to get your comments regarding our proposition for
network related hooks.
In general we are planning to prepare framework for future support of
bunch network related hooks.
Some of them already proposed by Itzik Brown [1] and Dan Yasny [2].
Below you can find the additional hooks list that we propose:
Note: In the first stage we can implement these hooks without any
parameters, just to provide an entry point
for simple hooks.
Networks manipulation:
- before_add_network(conf={}, customProperty={})
- after_add_network(conf={}, customProperty={})
- before_del_network(conf={}, customProperty={})
- after_del_network(conf={}, customProperty={})
- before_edit_network(conf={}, customProperty={})
- after_edit_network(conf={}, customProperty={})
- TBD
+ 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
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.
Bondings manipulations:
- before_add_bond(conf={}, customProperty={})
- after_add_bond(conf={}, customProperty={})
- before_del_bond(conf={}, customProperty={})
- after_del_bond(conf={}, customProperty={})
- before_edit_bond(conf={}, customProperty={})
- after_edit_bond(conf={}, customProperty={})
- TBD
General purpose:
- before_persist_network
- after_persist_network
Now we just need to figure out the use cases.
Your input more than welcome...
