1.1 Openstack Config SRIOV
Openstack configuration:
...
1. NIC configuration refer to https://docs.openstack.org/neutron/pike/admin/config-sriov.html
2. An example of a site having three types of compute nodes.
...
1st set of compute nodes have two SRIOV NIC cards with vendor/device id as 1234, 5678 and vendor/device id as 2345 &6789. 2nd set of compute nodes have two SRIOV-NIC of same type 4321 & 8765. And third set of compute nodes don't have any SRIOV-NIC cards. And hence Openstack administrator at the site creates three flavors to reflect the hardware the site has. As you see in this example, it is expected that
...
host aggregate format is followed.
...
The value supposed to be of the form "NIC-sriov-<vendor ID>-<device ID>-<Provider network>
