Hi, you can find how Metadata service is implemented here [0] using networking-ovn. The metadata agent will create a veth pair; one end is placed inside the ovnmeta namespace and the other is plugged into br-int. Quoting from the doc upstream: Creating a VETH pair (OVS upgrades that upgrade the kernel module will make internal ports go away and then brought back by OVS scripts. This may cause some disruption. Therefore, veth pairs are preferred over internal ports). From your paste in the bug description, you can see that only difference is the last character of the name: '1' for the OVS end and '0' for the namespace one: tap548adde8-f1 tap548adde8-f0 If you feel that we should clarify our docs, let's handle it as a documentation bug. What do you think? For now I'll reassign this to DFG:Docs but feel free to proceed as needed. [0] https://docs.openstack.org/networking-ovn/latest/contributor/design/metadata_api.html |
