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)
Rather than making all clients of monitor commands that are JSON-only
check whether yajl support was compiled in, it is simpler to just
avoid setting the capability bit up front if we can't use the capability.
* src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Only set
capability bit if we also have yajl library to use it.
* src/qemu/qemu_driver.c (qemuDomainReboot): Drop #ifdefs.
* src/qemu/qemu_process.c (qemuProcessStart): Likewise.
* tests/qemuhelptest.c (testHelpStrParsing): Pass test even
without yajl.
* tests/qemuxml2argvtest.c (mymain): Simplify use of json flag.
* tests/qemuxml2argvdata/qemuxml2argv-disk-drive-error-*.args:
Update expected results to match.
This patch teaches testutil how to read multi-line input files with
backspace-newline line continuation markers.
The patch also breaks up all the single-line arguments test input files into
multi-line files with lines shorter than 80 characters.
* Fixes per feedback from Dan and Daniel
* Added test datafiles
* Re-disabled JSON flags
* Added code to print the error policy attribute when generating XML
* Re-add empty tag
