[Openstack] [neutron][nova] vif_plugging_is_fatal significance?

I have a working openstack setup. But I have some questions on how I got it

Initially my instances failed to launch.

I have updated the correct values for neutron authentication in nova.conf
and correct nova authentication in neutron.conf and notify_nova on port
change is true but still instances failed.

One thing I did note was that It took an awfully long time to fail and by
the time it reported failure neutron had created a port for the instance,
the vif driver had created a tap interface, the kvm had already started but
still nova reported failure.

When I set vif_plugging_is_fatal to false and vif_plugging_timeout to 10 I
could finally have my Instances up and in about 20 seconds.

Someone please explain the
1, significance of these two parameters

2. what had been going on in my openstack before I had them configured

3. if even the configuration I had done is correct or am I just bypassing
some bigger problem.

Thank you,
Ageeleshwar K
