The libvirt driver now allows utilizing file backed memory for qemu/KVM virtual machines, via a new configuration attribute ``[libvirt]/file_backed_memory``, defaulting to 0 (disabled). ``[libvirt]/file_backed_memory`` specifies the available capacity in MiB for file backed memory, at the directory configured for ``memory_backing_dir`` in libvirt's ``qemu.conf``. When enabled, the libvirt driver will report the configured value for the total memory capacity of the node, and will report used memory as the sum of all configured guest memory. Running Nova with file_backed_memory requires libvirt version 4.0.0 and qemu version 2.6.0 This introduces parameters QemuMemoryBackingDir and NovaLibvirtFileBackedMemory Resolves-Bug: 1793687 Depends-On: I0d9eb21fcab01266e501b7fc63c5b2bbb244956a Change-Id: I47e2f92fb2ed3e66d4bf31814eac9090382ef4e1
