Weekly status #156

Weekly status for the week of the 6th of July to the 12th of July.



This past week’s highlight was the addition of SPICE visual console support for VMs. This is useful when using graphical OSes such as Windows.

You need to have a SPICE client installed on the machine where you run the lxc client. Either spicy or remote-viewer.

On Ubuntu this can be installed using:

sudo apt install spice-client-gtk

It can then be used as follows:

lxc start <VM instance> --console=vga
lxc console <VM instance> --type=vga

In addition to that there was the usual round of improvements and bug fixes.

  • Custom block volumes (added last week) now support migration.
  • VM hugepage support was improved.
  • ZFS auto trim support was added (see ZFS section of https://linuxcontainers.org/lxd/docs/master/storage#notes-and-examples for enabling support on existing pools).
  • The resources API now uses udev information for storage device model if available.
  • The resources API now reports on mediated GPU devices.
  • The documentation for LXD proxy devices has been improved.
  • An issue with LXD setups previously incompletely configured for clustering with a node address of “0” now preventing LXD startup has been fixed.
  • Command argument ordering was tweaked when using lxc aliases to allow arguments to be interpreted by lxc rather than the alias being executed.


LXC saw improvements to the PTY implementation and checkconfig output.


The yum manager gained support for --allowerasing flag to fix a CentOS 8 dependency resolution issue.
