[PATCH 1/2] Close all file descriptors in the recovery process.
From: "Richard W.M. Jones" <rjones at redhat.com>
If the parent process uses a pipe (or any fd, but pipes are a
particular problem), then the recovery process would hold open the
file descriptor(s) of the pipe, meaning that it could not be fully
closed in the parent. Because the recovery process doesn't use
exec(2), this wasn't avoidable even using FD_CLOEXEC.

modifying open_guest function (copy_over.c)
It works, but I should delete
if (guestfs_umount_all (destg) == -1)
??? exit (EXIT_FAILURE);
inmain() function and
/* Clean up. */
? if (guestfs_umount_all (srcg) == -1) {
??? pthread_cancel (threaddata->mainthread);
??? exit (EXIT_FAILURE);
? }
in the start_scrthread() function or it will return an error after the program finish:
libguestfs: error:...

[PATCH 0/7 v2] Fix and workaround for qcow2 issues in qemu causing data corruption.

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
