[libvirt] [PATCH v3 0/8] Support qemu-system-arm vexpress-a9

This series adds the bits needed to kick of a qemu-system-arm -machine vexpress-a9 guest. vexpress-a15 likely works as well but is untested. Patches 1-2 are related bugfixes/improvements. Patch 6 adds disk bus=sd, which is often the only way to specify storage for ARM boards. Patch 8 adds virtio-mmio address support, which enables virtio for ARM vexpress machine types. The rest are mostly about fixing CLI generations. Unfortunately qemu ARM boards don't quite work like x86 where we can mix and match devices, so -device is out of the picture (for non-virtio), meaning we have to fall back to CLI infrastrucure like -net nic and -serial. v3: Rebased series Add qemu.conf nographics_allow_host_audio for patch #1 Drop domain_conf.c default memballoon handling in patch #2, not #3 Cole Robinson (8): qemu: Set QEMU_AUDIO_DRV=none with -nographic domain_conf: Add default memballoon in PostParse callbacks qemu: Don't add default memballoon device on ARM qemu: Fix specifying char devs for ARM qemu: Don't try to allocate PCI addresses for ARM domain_conf: Add disk bus=sd, wire it up for qemu qemu: Fix networking for ARM guests qemu: Support virtio-mmio transport for virtio on ARM docs/formatdomain.html.in
