Dear All,
I am getting an error while creating SRIOV enabled instances following the
guide from Openstack pike
https://docs.openstack.org/neutron/pike/admin/config-sriov.html
I want to start an instance on openstack pike with SRIOV enabled NICs. However,
I am getting a Libvirt error regarding the node name. The error looks weird as
the node name is not matching the interface name on the host machine or in the
configuration files.

nova.compute.manager
The correct interface name is enp129s0f0. However, I am getting the node name
as net_enp129s2_b2_87_6e_13_a1_5e' which i believe is the reason behind the
failure of vm creation on openstack. Please if someone could help me understand
how the node name is passed on to the Libvirt from openstack or how can I
resolve this issue.
Regards,
Navdeep
