[Announce] virtio-fs released with Kata Containers support
by Stefan Hajnoczi 17 Jan '19

17 Jan '19

Dear Kata Containers Community, I'm delighted to announce the first release of virtio-fs, a new shared file system for virtual machines that is designed for container use cases, including shared volumes. Unlike virtio-9p and NFS over AF_VSOCK, virtio-fs aims to take advantage of the co-location between the virtual machine and the hypervisor in order to achieve local file system semantics and improve performance. For example, it can use Linux Direct Access (DAX) to access file contents directly from the host page cache. This reduces communication with the file server and avoids duplicating data into each sandbox VM. It also means that mmap MAP_SHARED on a shared volume is coherent between sandbox VMs. The Linux kernel code (including performance numbers) has been posted here: https://marc.info/?l=linux-fsdevel&m=154446243324255&w=2 Kata Containers integration is already available so you can benchmark and test virtio-fs. The project is under active development and we still expect to make significant changes based on feedback and collaboration. We hope virtio-fs is interesting as a next step in overcoming virtio-9p's performance and limitations. Let us know how it performs! You can read more about virtio-fs here: https://virtio-fs.gitlab.io/ The Kata HowTo is here: https://virtio-fs.gitlab.io/howto-kata.html The Kata runtime and agent changes are fairly straightforward and comparable to virtio-9p. There are several other code changes due to using a Fedora initramfs, systemd, and modular kernel. These are not essential to virtio-fs but are simply how I preferred to develop and test. The FAQ on the virtio-fs website explains the main technical features. Please let me know if you have any questions or need help getting it running! I'm also on #kata-dev IRC if you need a hand.

happy holidays. Herding ...
by Whaley, Graham 24 Dec '18

24 Dec '18

Good morning Kat'ers, As I'm sure you are all aware, we have just about entered the holiday season. In theory, the official herders according to https://github.com/kata-containers/community/wiki/Review-Team-Rota#the-rota Are... Carlos, along with some Elves, Reindeer and maybe Santa himself if he gets his rounds done... In reality, I suspect we will have no focused herders until maybe January the 2nd onwards... so... no matter where you are or what your plans are, I hope you all have a great break, and will see you back at the keyboard in the new year! Graham (and the rest of the Herders...) --------------------------------------------------------------------- Intel Corporation (UK) Limited Registered No. 1134945 (England) Registered Office: Pipers Way, Swindon SN3 1RJ VAT No: 860 2173 47 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

Kata release 1.5.0-rc2 now available
by Ernst, Eric 21 Dec '18

21 Dec '18

Happy winter-solstice-holiday-of-choice, kata-folk! I am very pleased to announce 1.5.0-rc2 release of the Kata containers project. See the release page<https://github.com/kata-containers/runtime/releases/tag/1.5.0-rc2> for details. This is an exciting release for Kata, which includes support for the Firecracker hypervisor, the s390x architecture as well as multiple fixes for shimv2 support. Firecracker has been tested with CRIO+Kubernetes as well as Docker (18.06), with support for multiple network interfaces as well as (block based) volumes. A block-based storage driver, such as devicemapper, is required when using Kata with Firecracker. See this issue<https://github.com/kata-containers/runtime/issues/1071> for details on current volume limitations. Firecracker is not currently packaged, but is available as part of our static-binary release tarball (available for download on the release page). I put together an initial wiki page with a quick start guide – take a look! Will work to get this into a proper repository after the holidays. https://github.com/kata-containers/documentation/wiki/Initial-release-of-Ka…<https://github.com/kata-containers/documentation/wiki/Initial-release-of-Ka…> There aren’t any changes for 1.3 or 1.4 stable branches at this time, so no release was made for these. Thanks for all the support on this release! -Eric

Kata packaging follow up
by Marco Vedovati 18 Dec '18

18 Dec '18

Hi, recently I've been working on updating kata packages with the goal to have them integrated into the official openSUSE repositories and to provide builds for more architectures. This is a report of the current status. I'd like to have some feedback from the community, and to know if you'd consider transitioning to this new packaging structure. Thanks, Marco Overview We created a new development project on OBS, named devel:kubic:katacontainers, that is supposed to host the most up-to-date packages version, and will be used as source to submit packages update to the official openSUSE repositories. Me, Jose Carlos, Eric, and Peng Tao are maintainers for this project. Here's the link: https://build.opensuse.org/project/show/devel:kubic:katacontainers Project content - katacontainers: this contains all the host-side components, i.e. the runtime, shim, proxy, ksm-throttler. I decided to have a single package grouping all the go host-side components, as all of them are needed to run kata containers on the host, and as of now there are no use cases where a user may want to cherry pick just some of them. - katacontainers-kernel: kernel for the VM. This is the same package as in home:katacontainers. - qemu-lite: this is the same package as in home:katacontainers. - kata-agent, kata-osbuilder, containment-rpm-kata: these are not meant to be installed on the host. They are consumed by OBS and kiwi in order to generate kata compatible VM images on OBS. There's also a subproject named devel:kubic:katacontainers:images, that's used to build kata VM images based on various distribution flavours. As of now it contains: - katacontainers-image-leap, katacontainers-image-tumbleweed: these are rootfs images, built using kiwi and based on the openSUSE Leap and Tumbleweed distributions. kiwi is able to build packages for other distributions, both RPM and DEB based, so expect more to be added. Supported Architectures The current status is that packages work fine on x86_64 and aarch64. I could not manage yet to find a suitable PPC machine to run tests. I also enabled builds for s390x, and most of the packages can build successfully on it. Open points - qemu-vanilla: I think that it should not be bundled with katacontainers. Each distribution should rely on its own QEMU version. - Clearlinux VM image: we could consider adding a pre-built x86_64 image. - Debian / Ubuntu packages: I did not work on updated dsc/control files, so it's something TODO. Contributors are welcome :) - Nightlies, stable versions: TODO.

KatHerders this week
by Whaley, Graham 17 Dec '18

17 Dec '18

Good morning. This week herders are: - Yash - Rico https://github.com/kata-containers/community/wiki/Review-Team-Rota#the-rota Yash, I know you are not too involved in the project at present - can you confirm if you will be able to dedicate us some time or not? Everybody else, things looked like they got busy at the end of last week - thanks for your dedication, and I suspect we will all need to help try to keep on top of things this week. ** HEADS UP ** And then, as you are all no doubt aware, Christmas is rapidly approaching, which means for many of us a major vacation period. I will predict that there will be few people online next Monday (24th), and unlikely to be back online until Wednesday January 2nd 2019 ! I also therefore don't think we will have any official herders next week (even if Carlos' name is in the table... ;-) ). Let's see how much stuff we can squash this week.... For those heading for a vacation then, may you have an excellent time!

Creation of OSF Project Confirmation Guidelines
by Claire Massey 13 Dec '18

13 Dec '18

Hi everyone, As you know, Kata Containers is a pilot project supported by the OpenStack Foundation (OSF). As such, we wanted to make sure you’re aware of an effort recently kicked off a sub group of the OSF Board of Directors to draft guidelines[1] for confirming pilot projects as full, top-level, open infrastructure project of the Foundation. The current pilot projects that will be eligible for confirmation review in 2019-2020 are Airship, Kata Containers, StarlingX and Zuul. Currently the OpenStack project is the only confirmed project. The discussion about drafting these guidelines is just getting started, and *we invite you to participate in this effort* by reviewing the working draft in this etherpad and adding in your feedback and thoughts starting on line 139: https://etherpad.openstack.org/p/BrainstormingOSFProjectConfirmationGuideli… There will most likely be an open call scheduled in early 2019 where additional feedback will also be welcomed. I will share that invitation with you once it’s schedule. The goal is to come up with a set of points that the Board can use when reviewing pilot projects for confirmation. This topic has previously been discussed at a very high-level at previous Board meetings, including the September 18th meeting[2] (starting around slide 38). 1. https://etherpad.openstack.org/p/ProjectConfirmationGuidelines 2. https://docs.google.com/presentation/d/10UyCpxkjPqC3kT-dYRpBxzNT39i2OhlggJv… <https://docs.google.com/presentation/d/10UyCpxkjPqC3kT-dYRpBxzNT39i2OhlggJv…> Thanks, Claire
