Support for SMP topology was added by qemu commit dc6b1c09849484fbbc50
prior to 0.12.0, our minimum supported qemu version.

a89f05ba8d qemu: Shorten per-domain directory names
Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca334).  However when the domain
name is long (let's say a ridiculous 110 characters), we cannot
connect to the monitor socket because on length of UNIX socket address
is limited.  In order to get around this, let's shorten it in similar
fashion and in order to avoid conflicts, throw in an ID there as well.
Also save that into the status XML and load the old status XMLs
properly (to clean up after older domains).  That way we can change it
in the future.

The shortening can be seen in qemuxml2argv tests, for example in the
hugepages-pages2 case.

51045df01b tests: Unconditionally enable QEMU_CAPS_DEVICE
QEMU_CAPS_DEVICE is always enabled for qemu binaries we support.
Sync qemuxml2* to match, and regenerate all test output.

d7db33bfe9 qemu: Specify format= iff disk source is not empty
Just recently, qemu forbade specifying format for sourceless
disks (qemu commit 39c4ae941ed992a3bb5). It kind of makes sense.
If there's no file to open, why specify its format. Anyway, I
have a domain like this:

    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

and obviously I am unable to start it. Therefore, a fix on our
side is needed too.

f81e0d480e qemu: assume -drive format is always available
As of QEMU 0.10.0 the -drive format= parameter was added,
so the QEMU driver can assume it is always available.

dc7f6c3d30 qemu: assume -uuid is always available
The -uuid arg was added in QEMU 0.10.0, so the QEMU driver can
assume it is always available.

f78610038d qemu: assume -drive argument is always available
As of QEMU 0.9.1 the -drive argument can be used to configure
all disks, so the QEMU driver can assume it is always available
and drop support for -hda/-cdrom/etc.

Many of the tests need updating because a great many were
running without CAPS_DRIVE set, so using the -hda legacy
syntax.

Fixing the tests uncovered a bug in the argv -> xml
convertor which failed to handle disk with if=floppy.

8afd34f2d8 tests: redo test argv file line wrapping
Back in

  commit bd6c46fa0c
  Author: Juerg Haefliger <juerg.haefliger@hp.com>
  Date:   Mon Jan 31 06:42:57 2011 -0500

    tests: handle backspace-newline pairs in test input files

all the test argv files were line wrapped so that the args
were less than 80 characters.

The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.

This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.

This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.

a216e64872 qemu: Set QEMU_AUDIO_DRV=none with -nographic
On my machine, a guest fails to boot if it has a sound card, but not
graphical device/display is configured, because pulseaudio fails to
initialize since it can't access $HOME.

A workaround is removing the audio device, however on ARM boards there
isn't any option to do that, so -nographic always fails.

Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately
this has massive test suite fallout.

Add a qemu.conf parameter nographics_allow_host_audio, that if enabled
will pass through QEMU_AUDIO_DRV from sysconfig (similar to
vnc_allow_host_audio)

195fa214b6 qemu: move -name arg to be 1st in "ps x" output
Currently, monitoring QEMU virtual machines with standard Unix
sysadmin tools is harder than it has to be. The QEMU command line is
often miles long and mostly redundant, it's hard to tell which process
is which.

This patch reorders the QEMU -name argument to be the first, so it's
immediately visible in "ps x", htop and "atop -c" output.

116d6af979 schema: rewrite seclabel rng to match code
The RNG for <seclabel> was too strict - if it was present, then it
had to have sub-elements, even if those didn't make sense for the
given attributes.  Also, we didn't have any tests of <seclabel>
parsing or XML output.

In this patch, I added more parsing tests than output tests (since
the output populates and/or reorders fields not present in certain
inputs).  Making the RNG reliable is a precursor to using <seclabel>
variants in more places in the XML in later patches.
