Putting the D in LXD: Why LXD Feels like a Hypervisor - Tycho Andersen, Canonical

Sign up or log in to save this to your schedule and see who's attending!

lxc move c1 host2:. In 18 characters, you can live migrate containers between hosts. LXD makes using this powerful and complex technology very simple, and very fast. In this talk, I'll give a short history of the underlying migration technology CRIU, describe a few optimizations that LXD is doing in the space to make things fast, and discuss future areas of work both in CRIU and in LXD to support a larger class of applications and make things even faster.

In addition to migration, LXD also offers APIs for containers to communicate with the hypervisor and query it for metadata (like cloud-init data). There are APIs to allow users to place files directly into a container's rootfs, and APIs to interactively start execute programs in a container (all over websockets!). This talk will cover all of these features and how they make LXD feel like a full blown hypervisor.
