LXD 5.1 has been released

28th of April 2022


The LXD team is very excited to announce the release of LXD 5.1!

This release comes with a lot of bugfixes following the LXD 5.0 LTS releases, all of which will also be in the upcoming LXD 5.0.1 LTS bugfix release. But don't worry, there are also a handful of new features.


New features and highlights

Sysinfo system call interception

A new security.syscalls.intercept.sysinfo option has been added which when enabled will cause LXD to intercept the sysinfo system call and emulate it.

This allows for values that would normally reflect the entire physical system to be replaced by values that properly reflect the container.

Depending on what software is used inside of the container, enabling this may result in better service configuration to respect the container's limits.

stgraber@dakara:~$ lxc launch images:alpine/edge a1 -c limits.memory=1GiB

Swap:             0           0           0

lxc cluster role sub-command

To help scripting the addition and removal of cluster member roles, a new lxc cluster role sub-command was added.

  stgraber@castiana:~$ lxc cluster role add celestis ovn-chassis
  stgraber@castiana:~$ lxc cluster role remove celestis ovn-chassis

lxc storage volume info shows volume total size

The lxc storage volume info command now shows both the Used size and the Total volume size when this one is known.

stgraber@dakara:~$ lxc storage volume create default foo size=5GiB
Storage volume foo created
stgraber@dakara:~$ lxc storage volume info default foo
Name: foo
Type: custom
Content type: filesystem
Usage: 192.00KiB
Total: 5.00GiB

Configurable host network interface naming pattern

A new instances.nic.host_name server configuration key allows changing the pattern used when creating new host side network interfaces.

By default LXD uses a random pattern which leads to interface names like vethXYZ or tapXYZ where XYZ is a completely random string of characters. This however does not make it very easy to track down a particular instance from the network name.

As an alternative, the new configuration option can now be set to mac which will lead to interface names including the most important part of the MAC address after a lxd prefix.

stgraber@dakara:~$ lxc launch images:alpine/edge a1
Creating a1
Starting a1
stgraber@dakara:~$ lxc info a1 | grep "Host interface"
      Host interface: veth0c1f893c
stgraber@dakara:~$ lxc config set instances.nic.host_name mac
stgraber@dakara:~$ lxc restart a1
stgraber@dakara:~$ lxc info a1 | grep "Host interface"
      Host interface: lxd163ecf0121

Overrideable evacuation mode

When evacuating a cluster member, LXD looks at the cluster.evacuate configuration key to determine what to do with each individual instance. This works great for normal cluster evacuations, but there are situations, such as wanting to shutdown an entire cluster, where one may want to override that action.

It's now possible with lxc cluster evacuate --action=stop which in this case will stop all instances regardless of their configuration. Do this on all of your cluster members and you'll be ready to shutdown your entire cluster. Once back up, use lxc cluster restore and the instances will start back up.

Setting profiles during an image copy

For quite a while now, LXD has supported assigning a list of profiles to a particular image such that any new instance created from the image would get those profiles applied (unless specifically overridden by the user).

Until now, this had to be setup through lxc image edit after the image was added to the image store.

This release now adds a new --profile flag to lxc image copy allowing for profiles to be added directly at image copy time.

stgraber@dakara:~$ lxc profile create foo
Profile foo created
stgraber@dakara:~$ lxc profile create bar
Profile bar created
stgraber@dakara:~$ lxc image copy images:alpine/edge local: --alias alpine --profile default --profile foo --profile bar
Image copied successfully!
stgraber@dakara:~$ lxc launch alpine a1
