If element A's callback waits for element B using aio_poll() it will

This is a part of a patch proposed by jaejunh at
https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1358268
which enables running ppc64le binaries through qemu-user.
Not sure if it's the right way to do it, but it does allow
me to chroot into a ppc64el rootfs on amd64 host.

I'm confused -- wouldn't these be handled by the existing
"ppc64le" support?

Hi,
After having debugged a hibernation BZ reported by QE, I got confused
about the support status of suspend/hibernate in RHEL7.
What I had in mind was that S3 was supported but S4 was not. Amit confirmed
that S4 is not supported in RHEL7, but:

Hi,
I won't have time to keep debugging this so I'll just report what I have.
The basic problem is: you suspend a Linux guest to RAM, and the screen
(or maybe the guest) freezes when resuming. Here's some debugging info:

v1.7.0: doesn't exactly freeze, but the

As can be seen in the final patch of this series, there are certain

039, 060 and 061 all create images with referenced clusters having a

these tests now have a different output. Fix it.
Furthermore, 060 created a refblock with a refcount greater than one

There are certain cases where repairing a qcow2 image might actually
damage it further (or rather, where repairing it has in fact damaged it
further with the old qcow2 check implementation). This should not
happen, so add a test for these cases.
Furthermore, the repair function now repairs refbloc
If a referenced cluster has a refcount of 0, increasing its refcount may
result in clusters being allocated for the refcount structures. This may

the refcount then.
In such cases, we can either try to replicate all the refcount
The previous commit introduced the "rebuild" variable to qcow2's

Because the old refcount structure will be leaked after having rebuilt
it, we need to recalculate the refcounts and run a leak-fixing operation
afterwards (if leaks should be fixed at all).
