Can you sprinkle some printfs() arount kvm_run (in qemu-kvm.c) to

Here's what I did:
interrupt exit requested
It appears from this you're using qemu.git. Please try qemu-kvm.git,
where the code appears to be correct.
Cc'ing qemu-devel now. For reference, here the initial problem description:
http://www.spinics.net/lists/kvm/msg48274.html
I didn't know there was another tree...
I have seen now a couple of suspends-while-reading with patches applied
to the qemu-kvm.git tree and indeed, when run with the same host kernel
and VM I do not see the debugging dumps due to double-reads that I would
have anticipated seeing by now. Now what? Can this be easily fixed in
the other Qemu tree as well?
One thing I'd like to mention is that I have seen what I think are
interrupt stalls when running my tests inside the qemu-kvm.git tree
version and not suspending at all. A some point the interrupt counter in
the guest kernel does not increase anymore even though I see the device
model raising the IRQ and lowering it. The same tests run literally
forever in the qemu.git tree version of Qemu.

Stefan
