[one-users] Dealing with port mirroring

[Jaime Melis]

Hi Carlos,

I think the proper way to do this is by configuring the port monitoring
automatically in the `post` open vswitch script:

https://github.com/OpenNebula/one/blob/one-3.8/src/vnm_mad/remotes/ovswitch/post
https://github.com/OpenNebula/one/blob/one-3.8/src/vnm_mad/remotes/ovswitch/OpenvSwitch.rb

What I would do is to add a custom value to the template, such as
PORT_MIRRORING="one-10;one-11"

Which will be read by the OpenvSwitch.rb and configure the port mirroring
of VMS one-10 and one-11. You could also hardcode in the driver a valid
user id, so that if it's not that user, no port mirroring will be set.

cheers,
Jaime
