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.
