Weekly status #220


Weekly status for the week of the 11th of October to the 17th of October.

Introduction

This past week has been mostly bug fixes and improvements as we continue working on our larger roadmap items. However LXD did get the ability to disable auto targetting of cluster members when creating new instances.

LXD

@stgraber has added another video, this time covering how to control resource usage of containers and virtual machines:

New features:

  • Added support for cluster member user configure keys (user.*).
  • Added support for disabling cluster member auto targeting via the scheduler.instance configuration key. Normally in a LXD cluster, when creating an instance, LXD will use auto targetting to select a cluster member to use to host the new instance. This can be overridden with the --target flag. However by setting scheduler.instance to manual you can now prevent certain cluster members from being candidates for auto targetting.

Improvements:

  • Rework OVN network static route management ready for the forthcoming peer connections feature. Routes are now added to OVN via a single command rather than one command per-route. We also have switched to nexthop port hints which will be needed for peer connections.
  • Removed unnecessary database lookups when checking whether a network is used by a particular NIC device.
  • Use consistent JSON encoding when communicating with QEMU via QMP socket.
  • Improvements to the database query generator (laying the groundwork for removing the reference table views).
  • Renames lxc cluster remove --quiet to lxc cluster remove --yes so that its not confused with the global --quiet flag.

Bug fixes:

  • Fix image copy between two remotes when source is not in default project.
  • Fixes an issue caused by a regression in QEMU 6.1 that broke CPU pinning.
  • Tries to load vfio-pci kernel module in all places needed.
  • Fixes a regression in the recent re-work of network record loading to support older networks that have a NULL description field.

LXC

Improvements:

  • Log terminal errors as warnings when they do not impact operation.

Bug fixes:

  • Fixes a regression in handling of lxc.cap.keep.

LXCFS

Bug fixes:

  • Fix padding for Slab entry in /proc/meminfo.

Distrobuilder

Bug fixes:

  • Fix RPM/Yum issue for Oracle Linux.

Dqlite (RAFT library)

Bug fixes:

  • Fix an issue that was causing assert crashes in LXD test suite.
  • Fix an issue that prevents accessing a NULL pointer.
  • Fix some memory segfaults.

LXD Charm

New features:

  • Adds cluster setup support.

Improvements:

  • Add support for metrics endpoint.

Youtube channel

We’ve started a Youtube channel with live streams covering LXD releases and its use in the wider ecosystem.

You may want to give it a watch and/or subscribe for more content in the coming weeks.
