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

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

doesn't make sense to require that binary file to just get version info
of that package in makefile.

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 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.

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

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.

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.

(VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING): New flag.

I'm about to make block stats optionally more complex to cover

may decide to add that later.

that libvirt creates per domain: the NVRAM variable store file.
Make sure that the file is not left behind if the domain is
undefined.

Coverity notes that after we VIR_ALLOC_N(params, nparams) a failed call to
virDomainGetCPUStats could result in nparams being set to -1. In that case,
the subsequent virTypedParamsFree in cleanup will pass -1 which isn't good.
Use the returned value as the number of stats to display in the loop as
it will be the value reported from the hypervisor and may be less than
nparams which is OK

Coverity points out that if 'dom' isn't returned from virDomainQemuAttach,
then the code already jumps to cleanup, so there was no need for the
subsequent if (dom != NULL) check.
I moved the error message about failure into the goto cleanup on failure
and then removed the if (dom != NULL)

Coverity points out that by using EMPTYSTR(type) we are guarding against
the possibility that it could be NULL; however, based on how 'type' was
initialized to NULL, then using nested ternary if-then-else's (?:?:)
setting either "ipv4", "ipv6", or "" - there is no way it could be NULL.
Since "-" is supposed to mean something empty in a field - modify the
nested ternary to an easier to read/process if-then-else leaving the
initialization to NULL to mean "-" in the formatted output.
Also changed the name from 'type' to 'typestr'.

Since 0766783abb
Coverity complains that the EDIT_FREE definition results in DEADCODE.
As it turns out with the change to use the EDIT_FREE macro the call to
vir*Free() wouldn't be necessary nor would it happen...
Prior code to above commitid would :
vir*Ptr foo = NULL;
...
foo = vir*GetXMLDesc()
...
vir*Free(foo);
foo = vir*DefineXML()
...
And thus the free was needed. With the change to use EDIT_FREE the
same code changed to:
vir*Ptr foo = NULL;
vir*Ptr foo_edited = NULL;
...
foo = vir*GetXMLDesc()
...
if (foo_edited)
vir*Free(foo_edited);
foo_edited = vir*DefineXML()
...
However, foo_edited could never be set in the code path - even with
all the goto's since the only way for it to be set is if vir*DefineXML()
succeeds in which case the code to allow a retry (and thus all the goto's)
never leaves foo_edited set
All error paths lead to "cleanup:" which causes both foo and foo_edited
to call the respective vir*Free() routines if set.

Tweak the messages so that they mention "title" rather than
"description" when operating in title mode. Also fixes one missing "%s"
before non-formatted gettext message.
Before:
$ virsh desc --title dom
No description for domain: dom
After:
$ virsh desc --title dom
No title for domain: dom

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.

The parser accepts P and E, so the formatter should too.

Commit c1d75de caused this warning on 32-bit platforms (fatal when
-Werror is enabled):
virsh-domain.c: In function 'cmdBlockCopy':
virsh-domain.c:2003:17: error: comparison is always false due to limited range of data type [-Werror=type-limits]
Forcing the left side of the < to be ull instead of ul shuts up
the 32-bit compiler while still protecting 64-bit code from overflow.

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.
