Hello,
I am adding some new hosts to my MOS 9.2 fuel deployment, and I want to implement dpdk on the 2 new hosts. I have fuel setup with the experimental options so I can see the settings when adding the new hosts.
My question is relating to the node attributes section. In the documents for showing how to setup dpdk, it states to setup nova cpu pinning along with the dpdk cpu pinning.
I get that the dpdk cpu pinning is the number of cpus allocated for processing of the packets based on nic speed.
I don't see any information on exactly what the value of nova cpu pinning should be when doing only dpdk (no sriov). When a vm is mapped to a flavor using dpdk, do all the vcpus the VM uses have to 'pinned' to use dpdk, thus this value means the total number of vcpus available to VMs needing dpdk?
I just want to make sure I understand these values when setting this up, so I do it correctly.
Thanks,
DG
