Hi,
maybe someone has an immediate idea or can reproduce, I'm currently
lacking time to debug this: With latest kvm-userspace I'm seeing
sporadic qemu crashes when hard-resetting a guest that currently does
some I/O (qcow2 disk in snapshot mode). Below is the backtrace, s is
null.
So far the issue does not show up with -no-kvm or with upstream qemu
(also without kvm as upstream's reset in kvm mode is not working yet).
I think I broke it -- cancellation assumes aiocbs were generated by
the block format driver, but there are now aiocbs that are generated
by the generic code.
The problem is in upstream as well, don't know why you don't see it
there (maybe you're seeing a different problem).
I'll come up with a patch.
Patchset just posted to qemu-devel.
