Description brimhall 2010-06-08 17:52:38 UTC
When I switched to 2.6.34 after being on 126.96.36.199 and below, my kvm-qemu winxp guest hanged consistently after being idle for ~30 minutes. I thought it was the kvm-qemu 0.12.4 which had also been upgraded, but after downgrading to kvm-qemu 0.12.3 and 0.11.1 I still saw the same behavior, so guessing the issue is with the kernel module. System details: debian "testing" amd64, intel i7-920, 6 Gb memory.

Any chance of a bisect to see what's the cause? 'git bisect start v2.6.34 v2.6.35 virt/kvm arch/x86/kvm' should get you there. Also of interest - 'info registers' of a hung guest - 'x /30i $eip - 30 of same

Sorry, the bisect command should be git bisect start v2.6.34 v2.6.33 virt/kvm arch/x86/kvm

Bug still open. Need to figure out how to do kvm-qemu console to get the output from the "info registers" above. -geoffb

Press alt-ctrl-2 in the qemmu window or start qemu-kvm with the option '-monitor stdio'
