libxl: add support for specifying clock offset and adjustment libxl supports setting the domain real time clock to local time or UTC via the localtime field of libxl_domain_build_info. Adjustment of the clock is also supported via the rtc_timeoffset field. The libvirt libxl driver has never supported these settings, instead relying on libxl's default of a UTC real time clock with adjustment set to 0. There is at least one user that would like the ability to change the defaults https://www.redhat.com/archives/libvirt-users/2018-February/msg00059.html Add support for specifying a local time clock and for specifying an adjustment for both local time and UTC clocks. Add a test case to verify the XML to libxl_domain_config conversion. Local time clock and clock adjustment is already supported by the XML <-> xl.cfg converter. What is missing is an explicit test for the conversion. There are plenty of existing tests that all use UTC with 0 adjustment. Hijack test-fullvirt-tsc-timer to test a local time clock with 1 hour adjustment. Signed-off-by: Jim Fehlig <jfehlig@suse.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>

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.
