Hi,
this is a heads-up, maybe someone has some time to look into this over
the day: I seems like the IO thread changes caused a few regressions to
the KVM mode.
When I keep this feature disabled, I see strange hick-ups of the event
delivery mechanism, and the guest stops once in a while for a second or
so. Attaching strace makes the whole process terminate early (looks like
it triggers a race in the signal handling). And when I enable the IO
thread, I immediately get a deadlock on qemu_global_mutex.
Moreover:
