which don't have multiple right variants (as e.g. "accension", which can
be both "accession" and "ascension"), such misspellings are left
untouched. The list of changes was manually re-checked for false

When libvirt is starting a domain, it reports the state as SHUTOFF until
it's RUNNING. This is not ideal because domain startup may take a long
time (usually because of some configuration issues, firewalls blocking
access to network disks, etc.) and domain lists provided by libvirt look
awkward. One can see weird shutoff domains with IDs in a list of active
domains or even shutoff transient domains. In any case, it looks more
like a bug in libvirt than a normal state a domain goes through.

The command did not modify the disk type and thus didn't allow to change
media from a file image to a block backed image or vice versa. In
addition when operating on a network backed removable devices the
command would replace the while <source> subelement with an invalid one.
This patch adds the --block option that allows to specify that the new
image is block backed and assumes that without that option all images
are file backed. Since network backends were always mangled it should
not cause problems.
Since cmdDetachDisk() calls into vshPrepareDiskXML() with
type == VSH_PREPARE_DISK_XML_NONE && source == NULL this would result
into skipping all the checks and effectively turn the function into a
XML formatter.
This patch changes the code to use the formatter directly so that the
function can be refactored in a easier way.
Wireshark supports pkg-config since 1.11.3. Right now we build
wireshark-dissectior tool as default trough rpm build only on
fedora >= 21 and there is new wireshark that supports pkg-config.
If someone wants to build libvirt with wireshark-dissector against old
wireshark, they should specify the location by hand.
This patch is mainly to fix wrong dependency on wireshark binary as it
doesn't make sense to require that binary file to just get version info
of that package in makefile.

Commit f182da20 (v1.2.6) caused a slight regression in virsh
reporting of a non-active block job; where it used to state
"Commit complete", it now states "Now in synchronized phase".

$ virsh iothread --help
NAME
iothreadpin - control domain IOThread affinity
SYNOPSIS
iothreadpin <domain> <iothread> <cpulist> [--config] [--live] [--current]
DESCRIPTION
Pin domain IOThreads to host physical CPUs.
OPTIONS
[--domain] <string> domain name, id or uuid
[--iothread] <number> IOThread ID number
[--cpulist] <string> host cpu number(s) to set
--config affect next boot
--live affect running domain
--current affect current domain
Using the output from iothreadsinfo, allow changing the pinned CPUs for
a single IOThread.
$ virsh iothreadsinfo $dom

If an invalid value is supplied or require option missing,
then an error will be displayed:
$ virsh iothreadpin $dom 4 3
error: invalid argument: iothread value out of range 4 > 3
$ virsh iothreadpin $dom 3
error: command 'iothreadpin' requires <cpulist> option
Now that qemuDomainBlocksStatsGather provides functions of both
qemuMonitorGetBlockStatsParamsNumber and qemuMonitorGetBlockStatsInfo we
can reuse it and kill a lot of code.
Additionally as a bonus qemuDomainBlockStatsFlags will now support
summary statistics so add a statement to the virsh man page about that.

Previously when a domain would get stuck in a domain job due to a
programming mistake we'd report the following control state:
$ virsh domcontrol domain
occupied (1424343406.150s)

We can use that to detect that the domain has an active job and report a
better error instead:

Modify the virsh man page to more accurately describe which values are
set by the virsh setmem and displayed by the virsh memtune or dominfo
based on the setmem command results.
A disk using a source pool is listed as having a source '-' in domblklist
because it doesn't check the right XML syntax to find the source.
Add a check for "./source/volume" which is where the "path" (of sorts)
to the volume name is described.
NUMA enabled guest configuration explicitly specifies memory sizes for
individual nodes. Allowing the virDomainSetMemoryFlags API (and friends)
to change the total doesn't make sense as the individual node configs
are not updated in that case.
Forbid use of the API in case NUMA is specified.

Well, imagine domains were running, and as the host went down, they
were managesaved. Later, after some time, the host went up again and
domains got restored. But without correct time. And depending on how
long was the host shut off, it may take some time for ntp to sync the
time too. But hey, wait a minute. We have an API just for that! So:
1) Introduce SYNC_TIME variable in libvirt-guests.sysconf to allow
users control over the new functionality
2) Call 'virsh domtime --sync $dom' in the libvirt-guests script.
Unfortunately, this is all-or-nothing approach (just like anything
else with the script). Domains are required to have configured and
running qemu-ga inside.

virsh's domdisplay command looks in /domain/devices/graphics/@listen
of the domain's XML for the listen address, however for listen
type='network' (added in libvirt 0.9.4), the <graphics> element
doesn't have a listen attribute, but has a <listen> subelement,
*still* with no address (this is the inactive XML):
<graphics type='spice' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
However, at domain start time the <listen> subelement gets its address
attribute filled in once libvirt figures out the IP address associated
with the named network (this is the status XML):
<graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
So in these cases, we need to look at
/domain/devices/graphics/listen/@address instead.
Even though another patch is being pushed that will backfill
listen/@address into @listen, this patch is still useful, as it fixes
domdisplay for cases of a new virsh (with this patch) connecting to a
libvirtd that is newer than 0.9.4 but doesn't have the followup patch.

The quality of error reporting from libxml2 varies depending
on the type of XML error made. Sometimes it is quite clear
and useful, other times it is obscure & inaccurate. At least
the user will see an error now, rather than having their
XML modification silently disappear.

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.
* include/libvirt/libvirt-domain.h
(VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING): New flag.
* src/libvirt-domain.c (virConnectGetAllDomainStats): Document it,

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
Domain: 'foo'
block.count=2
block.0.name=hda
