Weekly status for the week of the 6th January to the 12th of January.
Introduction
This past week our focus has been almost entirely on the new LXD storage layer with many bug fixes and improvements being merged. The big ticket item was the new ZFS storage driver.
In addition to that support for multiple VM NIC devices was added.
On the LXC front support for procfs has been removed, as all new features will depend on using anon-inode pidfs.
Additionally there was a change to the way veth devices are initiated. Rather than creating them in the host’s network namespace and then moving one end into the container’s network namespace, one end of the veth pair is now directly created inside the container’s network namespace. This allows us to work around a kernel permission bug that in combination with a recent change in systemd 244 causes uses of systemd-networkd to not get an ip address.
Finally a new command flag -v was added to LXCFS to allow the version number to be returned.
Contribute to LXD
Ever wanted to contribute to LXD but not sure where to start?
We’ve recently gone through some effort to properly tag issues suitable for new contributors on Github: https://github.com/lxc/lxd/labels/Easy
