This patch introduces access to allocation information about
a backing chain of a live domain.  While querying storage
volumes for read-only disks could provide some of the details,
we do NOT want to read() a file while qemu is writing it.
Also, there is one case where we have to rely on qemu: when
doing a block commit into a backing file, where that file is
stored in qcow2 format on a host block device, we want to know
the current highest write offset into that image, in order to
know if the disk must be resized larger.  qemu-img does not
(currently) show this information, and none of the earlier
block APIs were extensible enough to expose it.  But
virDomainListGetStats is perfect for the job!

We don't need a new group of statistics, as the existing block
group is sufficient.  On the other hand, as existing libvirt
releases already report 1:1 mapping of block.count to <disk>
devices, changing the array size could confuse older clients;
and even with newer clients, the time and memory taken to
report additional statistics is not always necessary (backing
files are generally read-only except for block-commit, so while
read statistics may change, sizing statistics will not).  So
the choice here is to add a new flag that only newer callers
will pass, when they are prepared for the additional information.

This patch introduces the new API, but it will take more
patches to get it implemented for qemu.

Commit id 'c9ffd3ea' updated the descriptions, but pointed at the
wrong place for the pool-define-as (it should have been pool-create-as)

I'm about to make block stats optionally more complex to cover
backing chains, where block.count will no longer equal the number
of <disks> for a domain.  For these reasons, it is nicer if the
statistics output includes the source path (for local files).
This patch doesn't add anything for network disks, although we
may decide to add that later.

With this patch, I now see the following for the same domain as
in the previous patch (one qcow2 file, and an empty cdrom drive):
$ virsh domstats --block foo

Total time of a migration and total downtime transfered from a source to
a destination host do not count with the transfer time to the
destination host and with the time elapsed before guest CPUs are
resumed. Thus, source libvirtd remembers when migration started and when
guest CPUs were paused. Both timestamps are transferred to destination
libvirtd which uses them to compute total migration time and total
downtime. Obviously, this requires the time to be synchronized between
the two hosts. The reported times are useless otherwise but they would
be equally useless if we didn't do this recomputation so don't lose
anything by doing it.

New --completed flag for virsh domjobinfo command.
Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

Expose the new power of virDomainBlockCopy through virsh (well,
all but the finer-grained bandwidth, as that is its own can of
worms for a later patch).  Continue to use the older API where
possible, for maximum compatibility.

The command now requires either --dest (with optional --format
and --blockdev), to directly describe the file destination, or
--xml, to name a file that contains an XML description such as:

<disk type='network'>
  <driver type='raw'/>
  <source protocol='gluster' name='vol1/img'>
    <host name='red'/>
  </source>
</disk>

[well, it may be a while before the qemu driver is actually patched
to act on that particular xml beyond just parsing it, but the virsh
interface won't need changing at that time]

Non-zero option parameters are converted into virTypedParameters,
and if anything requires the new API, the command can synthesize
appropriate XML even if the --dest option was used instead of --xml.

The existing --raw flag remains for back-compat, but the preferred
spelling is now --format=raw, since the new API now allows us
to specify all formats rather than just a boolean raw to suppress
probing.

I hope I did justice in describing the effects of granularity and
buf-size on how they get passed through to qemu.

* tools/virsh-domain.c (cmdBlockCopy): Add new options --xml,
--granularity, --buf-size, --format. Make --raw an alias for
--format=raw. Call new API if new parameters are in use.
* tools/virsh.pod (blockcopy): Document new options.

To date, anyone performing a block copy and pivot ends up with
the destination being treated as <disk type='file'>.  While this
works for data access for a block device, it has at least one
noticeable shortcoming: virDomainGetBlockInfo() reports allocation
differently for block devices visited as files (the size of the
device) than for block devices visited as <disk type='block'>
(the maximum sector used, as reported by qemu); and this difference
is significant when trying to manage qcow2 format on block devices
that can be grown as needed.

Of course, the more powerful virDomainBlockCopy() API can already
express the ability to set the <disk> type.  But a new API can't
be backported, while a new flag to an existing API can; and it is
also rather inconvenient to have to resort to the full power of
generating XML when just adding a flag to the older call will do
the trick.  So this patch enhances blockcopy to let the user flag
when the resulting XML after the copy must list the device as
type='block'.

Expose the new flag just added to virDomainGetBlockJobInfo.
With --raw, the presence or absence of --bytes determines which
flag to use in the single API call.  Without --raw, the use of
--bytes forces an error if the server doesn't support it,
otherwise, the code tries to silently fall back to scaling the
MiB/s value.

My goal is to eventually also support --bytes in bandwidth mode;
but that's a bit further down the road (and needs a new API flag
added in libvirt.h first).

This changes the human output, but the previous patch added
raw output precisely so that we can have flexibility with the
human output.  For this commit, I used qemu-monitor-command to
force an unusual bandwidth, but the same will be possible once
qemu implements virDomainBlockCopy:

Before:
Block Copy: [100 %]    Bandwidth limit: 2 MiB/s
After:
Block Copy: [100 %]    Bandwidth limit: 1048577 bytes/s (1.000 MiB/s)

The cache avoids having to repeatedly checking whether the flag
works when talking to an older server, when multiple blockjob
commands are issued during a batch session and the user is
manually polling for job completion.

* tools/virsh.h (_vshControl): Add a cache.
* tools/virsh.c (cmdConnect, vshReconnect): Initialize the cache.
* tools/virsh-domain.c (opts_block_job): Add --bytes.
* tools/virsh.pod (blockjob): Document this.

The current output of 'blockjob [--info]' is a single line
designed for human consumption; it's not very nice for machine
parsing.  Furthermore, I have plans to modify the line in
response to the new flag for controlling bandwidth units.
Solve that by adding a --raw parameter, which outputs
information closer to the C struct.

$ virsh blockjob testvm1 vda --raw
 type=Block Copy
 bandwidth=1
 cur=197120
 end=197120

The information is indented, because I'd like for a later patch
to add a mode that iterates over all the vm's disks with status
for each; in that mode, each block name would be listed unindented
before information (if any) about that block.

Now that we have a raw mode, we can guarantee that it won't change
format over time.  Any app that cares about parsing the output can
try --raw, and if it fails, know that it was talking to an older
virsh and fall back to parsing the human-readable format which had
not changed until now; meanwhile, when not using --raw, we have
freed future virsh to change the output to whatever makes sense.

My first change to human mode: this command now guarantees a line
is printed on successful use of the API, even when the API did
not find a current block job (consistent with the rest of virsh).

Bonus: https://bugzilla.redhat.com/show_bug.cgi?id=1135441
complained that this message was confusing:

$ virsh blockjob test1 hda  --async --bandwidth 10
error: conflict between --abort, --info, and --bandwidth modes

even though the man page already documents that --async implies
abort mode, all because '--abort' wasn't present in the command
line.  Since I'm adding another case where options are tied
to or imply a mode, I changed that error to:

error: conflict between abort, info, and bandwidth modes
