Version Compatibility

This file documents compatibility between versions of this project with XR releases. In some cases extra arguments will be required to continue using older XR releases, and those cases will be documented here.

v1.1

Supports XR versions 7.7.1 and above.

Versions with compatibility considerations are documented below.

XR 7.8.1

  • The real-time scheduling host check can be ignored before XR version 7.9.1.

XR 7.7.1

  • Does not support the --boot-log-level arg in launch-xrd.
  • Requires the host cgroup mount to be passed into the container manually:
    • Pass the docker/podman arguments --volume /sys/fs/cgroup:/sys/fs/cgroup:ro through launch-xrd.
    • Add the following under the 'service' section in an xr-compose topology: 
      volumes:
- source: /sys/fs/cgroup
  target: /sys/fs/cgroup
  type: bind
  read_only: True
  • Does not support running with --cgroupns=private.
  • Requires /sys/fs/cgroup/systemd/ to be mounted read-write on the host.
  • Does not support cgroups v2.
  • The real-time scheduling host check can be ignored before XR version 7.9.1.
