Hello, The LXD, LXC and LXCFS teams are very proud to announce their 4.0 LTS releases!
LTS versions of all 3 projects are released every 2 years, starting 6 years ago. Those LTS versions benefit from 5 years of security and bugfix support from upstream and are ideal for production environments. # LXD LXD is our system container and virtual machine manager. It's a Go application based on LXC and QEMU. It can run several thousand containers on a single machine, mix in some virtual machines, offers a simple REST API and can be easily clustered to handle large scale deployments. It takes seconds to setup on a laptop or a cloud instance, can run just about any Linux distribution and supports a variety of resource limits and device passthrough. It's used as the basis for Linux applications on Chromebooks and is behind Travis-CI's recent Arm, IBM Power and IBM Z testing capability. The main highlights for this release are (compared with 3.0): - Support for running virtual machines - Introduction of projects (and their limits, restrictions and features) - System call interception for containers - Backup/restore of instances (as standalone tarball) - Automated snapshots (and expiration) for instances and storage volumes - Support for "shiftfs" for instances and attached disks - New "ipvlan" and "routed" NIC types - CephFS as a custom volume storage backend - Image replication and multi-architecture support in clusters - Role based access control (through Canonical RBAC) - Full host hardware reporting through the much extended resources API - CGroup2 support - Nftables support 4.0.0 release announcement: https://discuss.linuxcontainers.org/t/lxd-4-0-lts-has-been-released/7231 Try LXD online: https://linuxcontainers.org/lxd/try-it/ Available images: https://images.linuxcontainers.org # LXC LXC is our container runtime. It's capable of running both system containers and application containers (OCI). It's written as a C library and set of tools with bindings available for a large number of languages, including go-lxc as used by LXD. The main highlights for this release are (compared with 3.0): - CGroup2 support - Infrastructure for system call interception - PIDfd support - Improved network handling - Hardening and refactoring throughout the codebase, fixing very many issues 4.0.0 release announcement: https://discuss.linuxcontainers.org/t/lxc-4-0-lts-has-been-released/7182 # LXCFS LXCFS is our FUSE filesystem. It's a daemon written in C which acts as an overlay usable inside containers to query the available host resources with cgroup constraints applied. It provides a variety of overlay files for /proc and /sys as well as a fully virtualized view of cgroupfs for distributions lacking cgroup namespacing support. The main highlights for this release are (compared with 3.0): - CGroup2 support - /proc/cpuinfo and /proc/stat based on cpu shares (--enable-cfs option) - /proc/loadavg virtualization (--enable-loadavg option) - pidfd supported process tracking (--enable-pidfd option) - Hardening of the codebase - Improved self re-execution logic with failsafe - More comprehensive testsuite (run on all architectures for all changes) 4.0.0 release announcement: https://discuss.linuxcontainers.org/t/lxcfs-4-0-lts-has-been-released/7031 4.0.1 release announcement: https://discuss.linuxcontainers.org/t/lxcfs-4-0-1-lts-has-been-released/7130 -- Stéphane _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
