[ANNOUNCEMENT] Kata Containers 1.4.0 release
Hello Kata-ers, I am happy to announce Kata Containers 1.4.0 release. It comes with several nice new features and many bug-fixes. All users are recommended to upgrade. The 1.4.0 release highlights following features: - Host cgroups support: qemu process and vcpu threads are now put in proper cpu cgroup in the host and cpu quota and period are used to constrain them. - NEMU `virt` machine type support: The new machine type is specially optimized for cloud environments and thus a great fit for Kata Containers use case. For more information about NEMU, see https://github.com/intel/nemu. - New NetInterworkingModel `none`: It works with tap endpoint types so that enlightened CNI plugins can add tap devices to a sandbox directly, bypassing host network namespaces and thus provide better performance with less network setup complexity. - New NetInterworkingModel `tcfilter`: Yet another method for Kata Containers to bridge the host netns veth and guest tap device, with TC filter rules. With it, Kata Containers have better compatibility with different network endpoint types. - Enable macvlan and ipvlan network support: These two networking models provide lightweight and fast access to underlay or host interfaces without NATTing. - Guest rootfs image can now have a `guest_hook_path` to save a bunch of prestart/poststart/prestop/poststop hook binaries, and they will be executed in the guest at specified container life cycle point accordingly. For full details, please see https://github.com/kata-containers/runtime/releases/tag/1.4.0 Kudos to all Kata community members for making it happen! Cheers, Tao -- bergwolf@hyper.sh

Is there jobs testing nemu in Jenkins?
