Greetings, Apologies for chiming in very late into the spec cycle. Netronome is completing its internal processes in order to allow developers to contribute code to OpenStack and we should be able to share patches within the week. Additional apologies for the long wall of text that's following.
We would really like to upstream support for our NICs in Pike. We've got patches that hook into core Nova (and make a tiny modification to the Neutron ML2 OVS mechanism plugin) to allow VM's to be plugged into our NIC's accelerated ports. The mechanism that we chose was to add another set of VNIC types (in the same group where VNIC_TYPE_NORMAL and VNIC_TYPE_DIRECT are defined), for the two separate plugging methods that we support. It's also very possible for us to just add one more (VNIC_TYPE_RELAY) and have everything work for us. (we also considered flavor and glance annotations, but chose this method for flexibility) We have two methods to plug VMs into the bridge. On Nova's side, they look either like vhost-user, or SR-IOV passthrough. On Neutron's side, everything look like an OVS bridge. Crucially, we support all three methods (standard TAP, SR-IOV and vhost-user) on the _same_ bridge, with SR-IOV and vhost-user accelerated, and with everything except SR-IOV being live-migrateable. I'm hoping that, by tomorrow, we'll have the necessary internal permissions in place to start discussing code. We'd appreciate any advice on processes and protocol to follow. Would it still be possible to jump on the Pike release? There is absolutely no emotional attachment to this code, so if a major redesign is on the cards, we'd be very agreeable to do so. Thanks again very much for reading this sizeable missive. I hope we can get on board and start contributing to OpenStack as soon as possible. (There's a lot of automatic tuning, pinning and scheduling support bits we'd like to contribute as well.) -- Jan Gutter Embedded Networking Software Engineer Netronome | First Floor Suite 1, Block A, Southdowns Ridge Office Park, Cnr Nellmapius and John Vorster St, Irene, Pretoria, 0157 Phone: +27 (12) 665-4427 | Skype: jangutter | www.netronome.com __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
