This, according to the presentation, comes in the form of a suite of VXLAN-related network interfaces. From two of the slides: vpc(4) Interfaces vpcsw(4) - switches packets - one packet per customer, multiple subnets supported in the same switch vmnic(4) - dedicated guest NIC, looks like a virtio network device to guests vpcp(4) - plugs vmnic(4) ports into vpcsw(4) switches vpci(4) - Non-bhyve(4) interface, usable in jails(2) ethlink(4) - Performs unencapsulated packet forwarding, wraps a cloned or physical ethernet interface vpclink(4) - Performs VXLAN encapsulation New System Calls vpc_open(2) - Creates a new VPC descriptor vpc_ctl(2) - Manipulates VPC descriptors Capsicum-like, intended for privilege separation Intended for idempotent tooling Makes aggressive use of UUIDs as operator handles to be compatible with Triton At the very end of the presentation slides are links to for kernel code and kernel library code on GitHub: https://github.com/joyent/freebsd/tree/projects/VPC https://github.com/joyent/freebsd/tree/projects/VPC/libexec/go/src/go.freebsd.org/sys/vpc Unfortunately, the whole repository on GitHub is gone. 404. And I couldn’t find any forks of it either. Does anyone have a copy of the VPC branch that Joyent had in that repository? All that seems to be left of the project on Joyent's GitHub is a separate, archived repository https://github.com/joyent/freebsd-vpc that only has code for a utility that would interact with the code from the aforementioned now gone repository.
