Hi, Malleshi,
I am not sure if you also use neutron with openvswitch plugin, well,
we once met similar problem on our testbed before, but it's because our
Neutron network node was also compute node, so, when virtual machine was
launched to neutron network node, after it injected vif into openvswitch
configuration, somehow it will cause both hypervisor and VM network to
be unstable(I didn't look into neutron code, presumingly, there is
conflict in openvswitch datapath configuration between VM and
hypervisor. ), I am not sure if that is also your case, but if you put
neutron network node and nova compute together, you might want to
separate neutron network from nova compute.
BTW, if you configure notify_nova_on_port_status_changes and
notify_nova_on_port_data_changes properly in nova.conf, you don't need
"vif_plugging_is_fatal: true"
Best regards,
Felix Lee ~

Hello Felix,
1. Which network service do you use?
Ans: Neutron
2. do you have separate network interfaces for VM instances and hypervisor?
Ans: Yes I do have 3 interfaces on compute node and network node .
1.eth0 : Management network
2.eth1: external network
3.eth2: for vm communication
Hypervisor used in nova-compute is KVM

Hi, Malleshi,
Which network service do you use?
Neutron or Nova network?
And, do you have separate network interfaces for VM instances and hypervisor?

I got the below error from horizon
*virtual interface creation failed *.
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*
is there method to fix this ..? Please let me know ,
