Hi,
[can you convince your mailer to wrap long lines?]
i have several vm's running on KVM hosts. Recently i found out that the
time in the log-files of the guests (/var/log/libvirt/qemu/xxx.log) is wrong. The time on the guest itself is right, just the time in the log-files is one hour back. Windows and linux vm's are affected. Also on another host the same. Changing the clock offset does not have any influence, still the wrong time in the log file.
The time in libvirt logs is ALWAYS tied to UTC, precisely because that is unambiguous (any log that outputs timestamps in local time risks being misinterpreted if the log is read from a different timezone, especially if the timezone name is not included as part of the timestamp). Based on you email address, it looks like your problem is that Germany is coincident with UTC in the summer, but one hour off in the winter, and that your "problem" (which is not a bug) was made manifest because Germany left daylight savings this week.
Nearly. In summer we have in germany UTC+2, in winter UTC+1.
