This flag will allow to use qemu guest agent commands to disable
(offline) and enable (online) processors in a live guest that has the
guest agent running.

The "cmd" argument in cmdList is now used. Unmark it as unused.

Commit 6e73850b support to set wwn for disks, but it was not
exposed to attach-disk.

Our documentation says a pool may be referenced by its name or UUID
anywhere if it makes sense (pool-name and pool-uuid are the only
exceptions). However, vol-create and vol-create-as commands did not obey
this.

Check the returned value for NULL and take the cleanup path
appropriately if the API fails.

Delay only makes sense with STP enabled.

Because it's a valid combination. p2p still uses a separate channel
for qemu migration, so there's value in letting the user specify a manual
migrate URI for overriding auto-port, or libvirt's FQDN lookup.

What _isn't_ allowed is --migrateuri and TUNNELLED, since there is
no separate migration channel. Disallow that instead

Use virMacAddrParse() to distinguish interface name from interface
mac address.

This adds a new option "--pretty" for qemu-agent-command, to
pretty-format the returned JSON string.

Automake already passes all CFLAGS to the linker too, so it
is not necessary to set WARN_LDFLAGS in addition to the
WARN_CFLAGS variable.

These all existed before virfile.c was created, and for some reason
weren't moved.

This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.

This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.

Recent commit '53531e16' resulted in a new Coverity warning regarding
a missing break in the ':' options processing. Adjust the commit to
avoid the issue.

Use virBufferAddLit or virBufferAddChar instead.

virAsprintf(&foo, "%s", bar) is wasteful compared to
foo = strdup(bar) (or eventually, VIR_STRDUP(foo, bar),
but one thing at a time...).

Noticed while reviewing Laine's attempt to clean up broken

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

Return 3 when the service is stopped, whether there
are saved guests or not, to conform with the LSB standards:

http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html

Mention file/volume contents instead of just 'file'/'volume'.

Also change Download->download in vol-download help,
to be consistent with other volume commands.

For long options, print:
* the option as specified by the user if it's unknown
* the canonical long option if its argument is not
  a number (and should be)

And for missing arguments, print both the short and
the long option name.
(Doing only one of those would require either parsing
argv ourselves or let getopt print the errors, since
we can't tell long and short options apart by optopt
or longindex)

'virsh help | grep nodedev-det' shows only nodedev-detach, but

The virsh nodedev-detach command has a new --driver option. If it's
given virsh will attempt to use the new virNodeDeviceDetachFlags API
instead of virNodeDeviceDettach. Validation of the driver name string
is left to the hypervisor (qemu accepts "kvm" or "vfio". The only
other hypervisor that implements these functions is xen, and it only
accepts NULL).

This patch factors out the vCPU count retrieval including fallback means
into vshCPUCountCollect() and removes the duplicated code to retrieve
individual counts.

The --current flag (this flag is assumed by default) now works also with
--maximum or --active without the need to explicitly specify the state
of the domain that is requested.

This patch also fixes the output of "virsh vcpucount domain" on inactive
domains:

Before:
$ virsh vcpucount domain
maximum      config         4
error: Requested operation is not valid: domain is not running
current      config         4
error: Requested operation is not valid: domain is not running

After:
$virsh vcpucount domain
maximum      config         4
current      config         4

.. and for transient domains too:

Before:
$ virsh vcpucount transient-domain
error: Requested operation is not valid: cannot change persistent config of a transient domain
maximum      live           3
error: Requested operation is not valid: cannot change persistent config of a transient domain
current      live           1

After:
$ virsh vcpucount transient-domain
maximum      live           3
current      live           1

Using of a incorrect value for the --holdtime option was silently
ignored and 0 was used. In case a negative number was used, it
overflowed as the API expects a unsigned int.

Fix the data type and getter function type and report errors on
incorrect values.

Rename the get_integer_keycode helper to vshKeyCodeGetInt and get rid of
a unneeded typecast.

With this patch, include public headers in "" form is only allowed
for "internal.h". And only the external tools (examples|tools|python
|include/libvirt) can include the public headers in <> form.

Explicitly state that using incomplete XML definition snippets for hot-management

As of 76d9f656 we are supporting two new modes: initctl and signal.
However, these are missing in help listing.
