Open Stack

Hi,

I am facing an issue with assigning SRIOV NICs to VMs in OpenStack Kilo environment deployed on Redhat 7.1.

I have deployed 3 control and two compute nodes in HA using Foreman. The compute nodes have Intel 82599 NICs .I have followed the following guide provided by RHEL to enable SR-IOV.

https://access.redhat.com/documentation/en/red-hat-enterprise-linux-openstack-platform/7/networking-guide/chapter-8-configure-sr-iov-networking

When I try to create a VM with SR-IOV NIC/Port the VM run into ERROR state. The error was similar when SRIOV ports were created on public and private networks in OpenStack. VMs created without SRIOV port are provisioned without any issue.

When a VM is provisioned with SRIOV NIC/Port, it runs into error state.The errors logged in neutron are given below this email.

Another peculiar behavior observed was, that changes in configuration files  (/etc/nova/nova.conf, /etc/neutron/plugin.ini, /usr/lib/systemd/system/neutron-server.service)  revert back to the default state when the services are restarted to apply changes. 

Am I doing something wrong? What steps do I need to overcome this issue? Please help.
