Background
In 4.10, we started to support OVS-DPDK workers by documenting and testing all the necessary steps to make it work on both UPI and IPI.
However, the process is all manual and involves:
- Configuring vhostuser on the right NIC in the workers so the NICs use VFIO-PCI driver
- Creating a directory to mount config-drive on the workers
- Enable vfio-noiommu on the workers, since QEMU doesn't support yet virtualized NOIOMMU (subject to change in the future).
- Manage the workers Machinesets and their scale (ie scale down workers and scale up with the new machineset so they're SR-IOV capable)
Also, in some use-cases (e.g. SR-IOV OVS-HW offload), the SR-IOV network webhook has to be disabled in order to let us create a SriovNetworkNodePolicy without error. Some work can be done in this webhook to support that use case.
Goals
- Document in both upstream (github/installer) and downstream (doc.openshift.com) these steps (this task is supposed to be done in 4.10, but we need to make sure everything is well documented)
- Make sure the webhook works fine when OVS-HW offload is configured in the SriovNetworkNodePolicy
- Design (in a document) an operator for OpenStack (e.g. OAO - OpenStack Addon Operator): what the operator would do and NOT do, how it would work, a proposal CRD, etc. And then present it to the DFG:NFV; collaborate and come to a joint decision to work on it or not.
- If we decide that an operator is needed, propose it as an openshift/enhancements and socialize it with the OpenShift community
- In the meantime and if time permits, we can prototype a basic operator, that wouldn't be supported in 4.11 anyway.
Acceptance Criteria
- Documentation of the manual steps are all documented (task from 4.10 that needs to be confirmed and/or improved in 4.11)
- The SR-IOV network operator webhook can be enabled for all our use-cases
- OAO proposal is documented, and presented to the OpenStack NFV team
- (optional) Enhancement is proposed and engagement is made with OpenShift community
- (optional) Prototype is demonstrating a basic feature (e.g. configuring vhostuser for the DPDK use-case)
