[Bug 790789] Re: KVM Guest freezing following Ubuntu update

I installed the 2.6.32-32 kernel in https://launchpad.net/~serge- hallyn/+archive/kernel and I see the same kvm guest crashes on my AMD Opteron host (the system in bug 799166) that I observed with the stock 2.6.32-32 kernel. wmldev@1p19l3j:~/standard_tests/test1$ aptitude show linux-image-2.6.32-

>From bug 799166: Current prerelease kernel 2.6.32-33 doesn't fix this issue for me. This issue is restricted to AMD processors. Falling back to 2.6.32-31 is an alternative work-around. For me, modifying the Linux command line in our guests is an undesirable workaround and I will be using 2.6.3

Ok, running the guest with clock=acpi_pm added to the Linux command line, whilst the host is running the 2.6.32-32 kernel has given me stable behaviour for 20 minutes with constant CPU usage, so it very much looks like this is a duplicate of bug 790789. -- You received this bug notification becau

Did the 2.6.32-33 kernel provided by Serge solve the issue? I see this report is for an AMD machine; it might possibly be related to https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/799166 although in that case there was no "kvm-clocksource has been installed" message in the logs prior to a

I've just noticed that although I refer to 2.6.32-32-server in my bug report, the Dell T105 for which I submitted the bug was running 2.6.32-32-generic. I have observed the same behaviour for 2.6.32-32-server on our other Dell T105 and confirmed that in each case, the crashes occur for 2.6.32-32 an

I made use of Mika's patch on a 10.04 system and found it solved my problem. I had been confused and thought that there was something wrong with my/the apparmor config for libvirt, because there were a few apparmor audit messages in the log, but in fact, it was this issue with the bridge interface
