[hybrid]: hang in update_wall_time
Hi Ian/Stefano: I changed over to the PV clock for hybrid liked we talked at the hackathon. I still have the hang in update_wall_time() after dom0 switches to xen as clocksource. The source of hang seems to be in xen stime_local_stamp in cpu_time that suddenly jumps to a large 64bit value. I''ve been chasing to figure where that happens, and why for the hybrid and not PV. It appears the source of jump is time_calibratio...

[PATCH 2/4] time: add a notifier chain for when the system time is stepped
From: David Vrabel <david.vrabel@citrix.com> The high resolution timer code gets notified of step changes to the system time with clock_was_set() or clock_was_set_delayed() calls. If other parts of the kernel require similar notification there is no clear place to hook into. Add a clock_was_set atomic notifier chain (clock_was_set_notifier_list) and call this in place of clock_was_set().

systemd-journald errors
Hi all, I have 5 CentOS 7 virtual guests installed (all fully patched to latest release) and i have the following error in all of them: systemd-journald[7779]: File /run/log/journal/b4a41f4214ca44f898638301891a6f2e/system.journal corrupted or uncleanly shut down, renaming and replacing. ?? .. And I don't understand why. I have configured "Storage=volatile" in journald.conf ...

Isolation and time
(Moving from offlist discussion.) I''m interested in opinions... Assume there are four single vcpu domains A, B, C, D, running on a 2-CPU physical machine. We wish to test for time skew on domain A. Assuming B, C, and D are all running some workload that attempts to fully saturate the (single) cpu. 1) Should the affect on domain A be essentially the same regardless of what load
