File 83edaf44-libxl-dont-hardcode-sched-weight.patch of Package libvirt.11330
commit 83edaf4435f9c2d1fa5afd1dfbb1643b4f564fd1 Author: Jim Fehlig <jfehlig@suse.com> Date: Thu Feb 22 11:52:56 2018 -0700 libxl: don't hardcode scheduler weight Long ago in commit dfa1e1dd53 the scheduler weight was accidentally hardcoded to 1000. Weight is a setting with no unit since it is relative to the weight of other domains. If no weight is specified, libxl defaults to 256. Instead of hardcoding the weight to 1000, honor any <shares> specified in <cputune>. libvirt's notion of shares is synonomous to libxl's scheduler weight setting. If shares is unspecified, defer default weight setting to libxl. Removing the hardcoded weight required some test fixup. While at it, add an explicit test for <shares> conversion to scheduler weight.
