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.

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.

assume it is always available.

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.

98e982b455 qemu: command: Make RNG backend device IDs unique
Libvirt didn't prefix the random number generator backend object alias
with any string thus the device alias and object alias were identical.

To avoid possible problems, rename the alias for the backend object and
tweak tests to comply with the change.

1c6999d340 conf: RNG: Always fill in default random source path for default backend
Libvirt documents that the default entropy source for the 'random'
backend of a RNG device is /dev/random. Instead of storing and
propagating NULL across our code and checking it in multiple places fill
the default in the post parse callback and use that in the other places.

be904e4eeb conf: Fix XML formatting of RNG device info
https://bugzilla.redhat.com/show_bug.cgi?id=1035118

When outputting the XML for the RNG device, the code didn't format the
PCI address info. Additionally the schema wasn't expecting the info
although it was being parsed and used internally. Fix those mistakes and
add test for the PCI info section.

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)

75e656a363 Fix crash parsing RNG device specification
Code that validates the whitelist for the RNG device filename
didn't account for fact that filename may be NULL. This led
to a NULL reference crash. This wasn't caught since the test
suite was not covering this XML syntax
