...e system will sometimes freeze for about 30 seconds and then continue; however, this could be related to kernel debugging that I have enabled. The only clock-related message in dmesg is: [ 153.483813] Clocksource tsc unstable (delta = -77312555973 ns) /sys/devices/system/clocksource/clocksource0/available_clocksource: xen jiffies tsc I can attach kernel config or other information as required. I have observed this on at least two platforms; the 2.6.32.x xen kernels do not exhibit this behavior. -- Daniel De Graaf National Security Agency _______________________________________________ Xen-devel mailing li...

...umber as your 'cpuKHZ' setting in your config.ini file?" There is no cpufreq directory under /sys/devices/system/cpu/cpu0; all I see is "cache" (dir), "crash_notes" (a file) and "topology" (dir). However under /sys/devices/system/clocksource/clocksource0, available_clocksource reads acpi_pm jiffies tsc pit, current_clocksource reads pit. (I put in the line clocksource=pit) in the grub boot up line. Divider=10 in the bootup line causes the boot up process to hang and a reset has to be performed; removing it and the CentOS boots properly. I'm currently using 2.6.18-...

...my entire Vista (x64 Ultimate) machine will BSOD when Ubuntu was booted with VMI turned on; only in the recent Workstation 6.0.3 patch that this bug has been fixed. For 3), Ubuntu default to vmi-timer if 1) and 2) are working properly; can be verified by /sys/devices/system/clocksource/clocksource0/available_clocksource and current_clocksource For 4), I didn't want to constantly lock the CPU of my laptop at highest speed at any time, as I don't need the CPU at full blast when I'm browsing website, or using MSOffice. So what I've done is by using distributed.net - this program uses idle CPU power t...

...nptd is running on the clients and that is able to correct this big mismatch. But what I don't understand is that the host does not seem to help the client with it's timekeeping. On a fedora16 machine I can tell that kvm-clock is being used: cat /sys/devices/system/clocksource/clocksource0/available_clocksource kvm-clock tsc acpi_pm cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock One the centos5 client I can think I see the same: dmesg|grep time.c time.c: Using 1.193182 MHz WALL KVM GTOD KVM timer. If I suspend a client, I see the time is correct just after resume. If I sa...

Hi, I have upgraded my Dell C151 to the latest 5.6. I have always used ntp to sync this machine and then the rest of the machines in the network would sync from it. Since the update I cannot keep the right time on the machine. This is with / without ntp. I have attempted various scenario's with no luck. I am now trying the old kernel now as I type this out. If anyone else has any

Hi there, I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof  or Oprofile. Is it possible to use some vtune

Dear fellow Xen''ers! I''m having a problem with my new Xen-enabled colocation server.. I hope ( at least ;) ) one of you guys know how to fix this problem.. For a certain amount of time ( 1-2 days ) the domU runs fine.. until the console starts spitting out messages like these: [80182.004456] clocksource/0: Time went backwards: delta=-6917292717540055641 shadow=80182004054805

Hi list! We currently have a PRI gateway composed by a box with two Digium quad-span PRI cards (a TE420 and a ). One of the cards is filled with TELCO1, while the other has first two slots filled with TELCO2, and 3rd slot with TELCO3. I am currently having (timer ?) issues on TELCO3 (span 7) D-Chan (202 as determined by dahdi_genconf ) is constantly failing causing on-going calls to terminate.

On a selection of boxes, ntpd running in Xen Dom0 reproducibly exhibits extermely high noise/jitter. Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise. Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0? Is the problem a config issue, or a bug? Already reported this downstream; everybody''s "stumped".
