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

[Zhu Guihua]

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
