[PATCH 0/7 v2] Fix and workaround for qcow2 issues in qemu causing data corruption.
https://bugzilla.redhat.com/show_bug.cgi?id=836710

There are at least two related bugs going on:
(1) Linux sync(2) system call doesn't send a write barrier to the
disk, so in effect it doesn't force the hard disk to flush its cache.
libguestfs used sync(2) to force changes to disk. We didn't expect
that qemu was caching anything
