41eb92783e virsh: add [--domain DOMAIN] option to domxml-to-native DOMAIN COMMAND
The option allows someone to run domain-to-native on already existing
domain without the need of supplying their XML.  It is basically
wrapper around 'virsh dumpxml  | virsh domxml-to-native /dev/stdin'.

c44482eb4f docs: correct improper information about domain states in virsh manpage
Commit 24d4a0a1f removed the non-existent "dying" state from the list
of possible domain states given in the virsh manpage, but didn't
correct the count of states from 8 down to 7. This patch fixes that
mismatch by completely removing any reference to the exact number of
states (thus preventing a potential future mismatch), while wording
the sentence in a more readable/truthful manner.

Similarly to previous commit, implement sparse streams feature

because we must implement a function that will tell us whether

ca21d75d25 virsh: add --io when attaching disks to guests
virt-install and virt-manager both default to explicitly setting
"io='native'" in the disk "driver" tag. virsh, however, does not and also
does not provide an option to specify that setting at all.  As a result,
disks use a different IO mechanism (the default, "threads") when attached
post-setup using virsh.  Adding this option allows users to keep disk
performance consistent for disks attached at install, and those attached
afterward.

4b9af8625a virsh-domain-monitor: add human readable output for 'domblkinfo'.
https://bugzilla.redhat.com/show_bug.cgi?id=1330940

The virsh command 'domblkinfo' returns the capacity, allocation and phisycal
size of the devices attached in a domain. Usually, this sizes are very big
and hard to understand and calculate. This commits introduce a human readable
support to check the size of each field easilly.

For example, the command before:

virsh # domblkinfo my_domain hda
Capacity:       21474836480
Allocation:     14875545600
Physical:       21474836480

and after this patch:

virsh # domblkinfo my_domain hda --human
Capacity:       20.000G
Allocation:     13.900G
Physical:       20.000G

a48c674fba storage: Move and rename disk backend label checking
Rather than have the Disk code having to use PARTED to determine if
there's something on the device, let's use the virStorageBackendDeviceProbe.
and only fallback to the PARTED probing if the BLKID code isn't built in.

This will also provide a mechanism for the other current caller (File
System Backend) to utilize a PARTED parsing algorithm in the event that
BLKID isn't built in to at least see if *something* exists on the disk
before blindly trying to use. The PARTED error checking will not find
file system types, but if there is a partition table set on the device,
it will at least cause a failure.

Move virStorageBackendDiskValidLabel and virStorageBackendDiskFindLabel
to storage_backend and rename/rework the code to fit the new model.

Update the virsh.pod description to provide a more generic description
of the process since we could now use either blkid or parted to find
data on the target device.

f23d4bbce3 storage: Fix implementation of no-overwrite for file system backend
https://bugzilla.redhat.com/show_bug.cgi?id=1363586

Commit id '27758859' introduced the "NO_OVERWRITE" flag check for
file system backends; however, the implementation, documentation,
and algorithm was inconsistent. For the "flag" description for the
API the flag was described as "Do not overwrite existing pool";
however, within the storage backend code the flag is described
as "it probes to determine if filesystem already exists on the
target device, renurning an error if exists".

The code itself was implemented using the paradigm to set up the
superblock probe by creating a filter that would cause the code
to only search for the provided format type. If that type wasn't
found, then the algorithm would return success allowing the caller
to format the device. If the format type already existed on the
device, then the code would fail indicating that the a filesystem
of the same type existed on the device.

The result is that if someone had a file system of one type on the
device, it was possible to overwrite it if a different format type
was specified in updated XML effectively trashing whatever was on
the device already.

This patch alters what NO_OVERWRITE does for a file system backend
to be more realistic and consistent with what should be expected when
the caller requests to not overwrite the data on the disk.

Rather than filter results based on the expected format type, the
code will allow success/failure be determined solely on whether the
blkid_do_probe calls finds some known format on the device. This
adjustment also allows removal of the virStoragePoolProbeResult
enum that was under utilized.

If it does find a formatted file system different errors will be
generated indicating a file system of a specific type already exists
or a file system of some other type already exists.

In the original virsh support commit id 'ddcd5674', the description
for '--no-overwrite' within the 'pool-build' command help output
has an ambiguous "of this type" included in the short description.
Compared to the longer description within the "Build a given pool."
section of the virsh.pod file it's more apparent that the meaning
of this flag would cause failure if a probe of the target already
has a filesystem.

So this patch also modifies the short description to just be the
antecedent of the 'overwrite' flag, which matches the API description.
This patch also modifies the grammar in virsh.pod for no-overwrite
as well as reworking the paragraph formats to make it easier to read.

no VIR_DOMAIN_DYING state then, there wasn't one when those lines of
virsh.pod were tweaked in 2008, and there still isn't one
