Possible hint for "Clocksource tsc unstable" problem
Hello, I made an interesting observation related to the "Clocksource tsc unstable (delta = -2999660320319 ns)" problem. In the log of ntpd I found: Oct 5 03:46:35 greenville-dom0 ntpd[4020]: kernel time sync status change 6001 Oct 5 04:03:41 greenville-dom0 ntpd[4020]: kernel time sync status change 2001 Oct 5 05:29:03 greenville-dom0 ntpd[4020]: kernel time sync status change

Kernel panic with 2.6.32-30 under network activity
Hello, I''ve got several kernel panic on a domU under network activity (multiple rsync using rsh). I didn''t manage to reproduce it manually, but it happened 5times during the last month. Each time, it is the same kernel trace. I am using Debian 5.0.8 with kernel/hypervisor : ii linux-image-2.6.32-bpo.5-amd64 2.6.32-30~bpo50+1 Linux 2.6.32 for 64-bit PCs ii

Xen 4.0.x 3,000 second time skew problem
...tp0 kernel: [9339489.266542] Clocksource tsc unstable (delta = -2999660317697 ns) or perhaps the kernel doesn''t notice but ntpd does: ls0 ntpd[15009]: time reset -2999.683517 s the point is it does affect all guests. Back in February 2011 there was a thread started by Olivier Hanesse which appears to be exactly the same issue: http://old-list-archives.xen.org/archives/html/xen-users/2011-02/msg00609.html Like Olivier, one of my hosts used to run Xen 3.x and did not experience this issue until after it was upgraded to Xen 4. The other has only ever run 4.0.x so I don'&...

(XEN) Platform timer appears to have unexpectedly wrapped 10 or more times.
Hi, Sometimes, seemingly randomly, long-running Xen domains, using clocksource xen, have their clock shift by ~3000 or ~36000 seconds, often with the dom0 complaining about clocksource tsc. The number changes if the hypervisor is explicitly told to use clocksource=pit, but it still happens. It doesn''t seem to be particularly hardware-specific. See also http://bugs.debian.org/599161 I

Debian/squeeze: domU live migraton hangs
Hi, In view of the problems I was having with DomU network timeout after a live migration (I posted that problems here a while ago but never got anything except from private emails) I finally updated my Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to 2.6.32-26. Now live migration just hangs...Any ideas? Xen-related Debian packages (all from Debian repositary, except drbd

DomU clock out of sync
Hey all, I was watching some logs on a domU today and i suddenly noticed that the timestamps were off by something on the order of 47 seconds. I was surprised because *I don''t* run independent wall clocks. I checked some other domUs and the "drift" was also very close to that of the first domU. I also checked another dom0, Here the domUs were "only" out of sync by
