Open Stack

Hi 

Some months ago I found this bug:
https://bugs.launchpad.net/nova/+bug/1467734/comments/2 [6] 

I wordarounded the bug setting in nova.conf of compute nodes
vif_plugging_is_fatal=false . 

Look for the string WTF here:
https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/master/etc_ansible/roles/kvm-hypervisor/templates/nova.conf_centos7.j2
[7] 

Maybe this can help.
