[libvirt] [PATCH 00/14] Introduce NVDIMM support

[Michal Privoznik]

NVDIMMs are new type of ultra fast storage that's plugged into DIMM slot and
can hold the stored info throughout reboots. After all, NV stands for
non-volatile. In virtualization world, this has an awesome advantage - less
VM_EXITs on 'disk' IO.

Currently, there is no NVDIMM namespace support. I think qemu does not support
it either.

Michal Privoznik (14):
  qemu_cgroup: Only try to allow devices if devices CGroup's available
  qemuBuildMemoryBackendStr: Reorder args and update comment
  Introduce NVDIMM memory model
  qemu: Introduce QEMU_CAPS_DEVICE_NVDIMM
  qemu: Implement NVDIMM
  conf: Introduce @access to <memory/>
  qemu: Implement @access for <memory/> banks
  security_dac: Label host side of NVDIMM
  security_selinux: Label host side of NVDIMM
  security: Introduce internal APIs for memdev labelling
  secdrivers: Implement memdev relabel APIs
  qemu_hotplug: Relabel memdev
  qemu: Allow nvdimm in devices CGroups
  qemu: Namespaces for NVDIMM
