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
lxcaliases to allow arguments to be interpreted by
lxcrather 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.
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: Easy issues for new contributors
- Nothing to report this week
The list below is feature or refactoring work which will span several weeks/months and can’t be tied directly to a single Github issue or pull request.
- Virtual machine support
- Distrobuilder Windows support
- Various kernel work
- Stable release work for LXC, LXCFS and LXD
The items listed below are highlights of the work which happened upstream over the past week and which will be included in the next release.
- Fix custom block volume migration
- terminals: update terminology again
- doc/instances: Improves proxy docs
- lxc/main_alias: Handle leading arguments
- units: handle multiplication integer overflow
- lxd/rbac: Always allow internal cluster traffic
- lxd/rsync: Untangle from daemon package
- lxd/qemu: Don’t use file.locking with rbd
- lxd/storage/zfs: Use autotrim when available
- lxd: Add clustering_fix_raft_address_zero patch to fix node with “0” as address
- lxd/resources: Use udev model data if available
- Decode error
- Report GPU mdev
- lxd/qemu: Fix unbound hugepages
- Spice console
- lxd/qemu: Properly connect memory
