Re: [libvirt] [PATCH v4 1/2] qemu: add support for dtb option

Signed-off-by: Olivia Yin <hong-hua.yin(a)freescale.com&gt; The "dtb" option sets the filename for the device tree. If without this option support, "-dtb file" will be converted into <qemu:commandline> in domain XML file. For example, '-dtb /media/ram/test.dtb' will be converted into <qemu:commandline> <qemu:arg value='-dtb'/> <qemu:arg value='/media/ram/test.dtb'/> </qemu:commandline> This is not very friendly. This patchset add special <dtb> tag like <kernel> and <initrd> which is easier for user to write domain XML file. <os> <type arch='ppc' machine='ppce500v2'>hvm</type> <kernel>/media/ram/uImage</kernel> <initrd>/media/ram/ramdisk</initrd> <dtb>/media/ram/test.dtb</dtb> <cmdline>root=/dev/ram rw console=ttyS0,115200</cmdline> </os> --- src/qemu/qemu_capabilities.c | 6 ++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 6 ++++ tests/qemuxml2argvdata/qemuxml2argv-ppc-dtb.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-ppc-dtb.xml | 28 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 2 + 6 files changed, 44 insertions(+), 0 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-ppc-dtb.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-ppc-dtb.xml
