Weekly status #137


Weekly status for the week of the 24th February to the 1st of March.

Introduction

This week some of the LXD team are meeting in Frankfurt for an engineering sprint.

In the past week LXCFS has gained support for cgroupv2 (to the extent that cgroupv2 allows it) and has been extensively restructured.

On the LXD front, work has continued on removing the old storage layer and updating any references to it to use the new storage layer.

There was also a series of patches for VM disk management that ensures that the GPT alternative header is moved to the end of the disk when creating and resizing VMs as is required by the GPT spec and to avoid kernel log warnings. This also highlighted an issue with ZFS volmode not being respected that was worked around.

An unnecessary filesystem creation step for VM disks was removed for LVM and Ceph volumes.

An issue with old log removal also removing the VM control socket file has been fixed.

Additionally an issue with backup tarball creation when the container filesystem contained a specific symlink has also been fixed.

On the LXC front a regression in the lxc.cgroup.pattern config setting was fixed.

Work also continued on adding VM image building support to distrobuilder, including adding lxd-agent inside the images.
