Hi list, recently I've been hitting some KVM bugs others seem to have reported as well, including
- CIFS timeouts - Stuck ?? errors - Random segmentation faults in the guest so I figured, I'll put together a stress test that can be used to reproduce these issues. This is done by using a CIFS mount on the host and unpacking data from that mount to the mount. I have been able to bring kvm down to its knees a lot just by doing this. Simply run the test in an endless-loop. FWIW enabling NPT helps triggering the issue. The guest kernels included here are openSUSE 11.0 (2.6.25) and 11.1 (2.6.27) kernels. Find the tests here: http://alex.csgraf.de/kvm-tests.tar.bz2 And some logs here (NPT enabled): http://alex.csgraf.de/kvm-logs.tar.bz2 I'm somewhat lost on the reason for these failures, so if you do have some time on your hands, please give me a hand debugging this! If I'd had to guess, I'd say it's either an APIC issue and/or guest memory corruption.
