Re: [libvirt] [PATCH v3 8/8] qemu: Support virtio-mmio transport for virtio on ARM

Starting with qemu 1.6, the qemu-system-arm vexpress-a9 model has a hardcoded virtio-mmio transport which enables attaching all virtio devices. On the command line, we have to use virtio-XXX-device rather than virtio-XXX-pci, thankfully s390 already set the precedent here so it's fairly straight forward. At the XML level, this adds a new device address type virtio-mmio. The controller and addressing don't have any subelements at the moment because we they aren't needed for this usecase, but could be added later if needed. Add a test case for an ARM guest with one of every virtio device enabled. --- src/conf/domain_conf.c | 12 +++- src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 17 ++++-- src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_command.c | 65 +++++++++++++++++----- .../qemuxml2argv-arm-vexpressa9-virtio.args | 14 +++++ .../qemuxml2argv-arm-vexpressa9-virtio.xml | 45 +++++++++++++++ tests/qemuxml2argvtest.c | 4 ++ 8 files changed, 139 insertions(+), 21 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-virtio.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-virtio.xml
