I got the below error from horizon

As per the link https://ask.openstack.org/en/question/26985/icehouse-virtual-interface-creation-failed/
If I add below entries in my nova.conf , I am able to launch a instance but I ll be disconnected from my host machine and I will not be able to connect via ssh aslo ... again I need to reboot my host  machine to connect ..
vif_plugging_is_fatal: false
vif_plugging_timeout: 0

Regards,
Malleshi CN
