[openstack-dev] [nova] Create a network filter

Hi all,

I'm using OpenStack together with OpenDaylight to add a network awareness
feature to the scheduler.
I have 3 compute nodes (one of these is also the Openstack Controller)
connected by a openvswitch controlled by OpenDaylight.
What I would like to do is to write a filter to check if a link is up and
then assign weight acconding to the available bw (I think I will collect
this data by ODL and update an entry in a db).
For each host I have a management interface (eth0) and an interface
connected to the OVS switch to build the physical network (eth1).
Have you got any suggestion to check the link status?
I thought I can be inspired by the second script in this link
to verify if the iface is up and then check the connectivity but It has to
be run in the compute node and I don't know which IP address I could point

Thank you

Silvia Fichera
