...on bare metal and it seems okay with that. Reproduced below is full serial console output of boot of hypervisor and dom0 kernel. I''ve indicated the points where progress seems to halt or be abnormally slow. The boot ends with a repeated message of: [10065189777.645584] CE: xen increasing min_delta_ns to 7197131137619773666 nsec [10065189777.645584] CE: xen increasing min_delta_ns to 1572324669574884690 nsec etc. Between this and some other messages about timers earlier on I gather there are timer problems here at the very least. If anyone has any suggestions for boot parameters that may allow...

...the same: sometimes VM hang at startup, SysRq-T shows modprobe waiting in "wait_for_devices" (concretely schedule_timeout) and jiffies counter not increasing between task-states dumps. The only found thing (probably) connected with this problem are domU kernel messages: CE: xen increased min_delta_ns to 150000 nsec (...) CE: xen increased min_delta_ns to 4000000 nsec CE: Reprogramming failure. Giving up This messages doesn''t exists in successful boot. I''ve also tried some options to xen and domU kernel, but without success (all combinations): xen: tsc=unstable, cpufreq=none...

...http://xenbits.xen.org/hg/xen-4.0-testing.hg/rev/ab1fb1b8b569?revcount=480 I have attached Keir's changeset as fix_bind_irq_vector_destination.patch. Here follows a portion of my dom0 serial console output to the point where booting becomes incredibly slow, and then the later "increasing min_delta_ns" spam, just in case that helps someone searching their own issue. The full logs are available in the xen-devel post linked above.

This is problem 1 of 3 problems we are having with live migration and/or ACPI on Xen-4.3 and Xen-4.2. Any help would be appreciated. Detailed description of problem: We are using Xen-4.3-rc1 with dom0 running Ubuntu Precise and 3.5.0-23-generic kernel, and domU running Ubuntu Precise (12.04) cloud images running 3.2.0-39-virtual. We are using the xl.conf below on qemu-upstream-dm and HVM and

I compiled linux-2.6 from git.

...counter value is too close to the comparator value to be reprogrammed the expected HPET intr may be missing. Linux kernel uses a mininal 48-hpet-ticks(~3.5us) distance to workaround this, but personal observation showed there is still failure case while delta=0xba (~13.5us). So choosing 20us as the MIN_DELTA_NS should be helpful to prevent near-missing from happening. local_irq_save/restore were used to avoid disturbance. (+ 2) was used as a final guard to avoid wrong judgement due to the real happened near-missing case. Signed-off-by: Wei Gang <gang.wei@intel.com> Signed-off-by: Tian Kevin <ke...
