That commit isn't in qermu-kvm-1.1.1.
It is in kernel.
Sorry, so it is.
With kernel 3.5.0 with b2da15ac26a0c00 reverted, I have just had 15
clean invocations of vanilla qemu-kvm-1.1.1. So that commit would seem
to be the problem.
Just to be sure, I've run some more tests today. No crashes occurred in
20 runs of vanilla qemu-kvm-1.1.1 on kernel 3.5.0 with b2da15ac26a0c00
reverted.
Ok. I'm trying to reproduce it here on a nested-virt setup, since the
code looks correct.
What's your preemption settings?
[chris:~/kernel/linux-3.5.0]$ grep PREEMPT .config
CONFIG_TREE_PREEMPT_RCU=y
CONFIG_PREEMPT_RCU=y
CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
CONFIG_PREEMPT_COUNT=y
