rtc: lost some interrupts at 1024Hz

[VinzC]

Hi.

I'm seeing this message in my system's log mostly when I run virtual machines be it under VMWare or Qemu (I haven't tried other virtualization environments yet):

Thanks for your suggestion. I felt something like Low latency desktop might fix this but I hesitated for I wonder what eats up CPU time like this. In fact everytime I use Qemu or VMWare Server with recent kernels (2.6.20 and above) I see messages like this one.

Most of all, I also have such messages on an IBM server with dual Intel Xeon 3 GHz and hyperthreading. The virtual machine is a Windows 2000 Advanced Server. It started to produce rtc lost interrupts after I promote the server as a domain controller. In the meantime the VM clock started drifting, producing even more of these messages... As a result the clock drift prevented the domain controller from reaching the domain afterwards and I got numerous messages in the VM event log saying Windows time service was not synchronized.

Do you think I should also use Low latency desktop on the IBM host server?

what exactly was the fix for this issue? it seems the reply to your original post was removed.

im having the same problem; surely others would appreciate a documented solution as well.

thanks

I don't know what the solution was in fact. All I did was to use a recent kernel, like Gentoo Sources 2.6.23 series. I haven't got such messages anymore.
