[libvirt] [RFC PATCH 00/11] qemu: add support to hotplug memory device

Now qemu has already supported memory hotplug, so this patchset will make libvirt support hotplug memory device for qemu driver. First, add two parameters slots and maxmem for memory hotplug, and the xml format can be like this. <memory slot='10'>102400</memory> <maxMemory>1024000</maxMemory> Second, memory device's xml format can be like this. <dimm driver='pc-dimm' addr='0' node='0' slot='1'> <backend type='ram' size='131072'/> </dimm> Zhu Guihua (11): domain_conf: support slots and maxmem properties in memory xml domain_conf: introduce virDomainDimmGetFreeSlot domain_conf: add support for memory device configuration in XML domain_conf: introduce dimm def helpers domain_conf: introduce dimm device hotplug helpers qemu: implement dimm device hotplug on config level qemu_monitor: introduce qemuMonitorAddMemoryBackend qemu_command: introduce a func for memory device alias qemu: implement support for pc-dimm qemu: introduce qemuBuildDimmDeviceStr qemu: implement dimm device hotplug on live level src/conf/domain_conf.c | 306 ++++++++++++++++++++++++++++++++++++++++++- src/conf/domain_conf.h | 54 ++++++++ src/libvirt_private.syms | 6 + src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 110 +++++++++++++++- src/qemu/qemu_command.h | 7 + src/qemu/qemu_driver.c | 26 ++++ src/qemu/qemu_hotplug.c | 71 ++++++++++ src/qemu/qemu_hotplug.h | 5 + src/qemu/qemu_monitor.c | 54 ++++++++ src/qemu/qemu_monitor.h | 4 + 12 files changed, 644 insertions(+), 3 deletions(-) -- 1.9.3
