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.
