The @option{id} parameter is a +unique ID that will be used to reference this memory region +when configuring the @option{-numa} argument. The @option{size} +option provides the size of the memory region, and accepts +common suffixes, eg @option{500M}. The @option{mem-path} provides +the path to either a shared memory or huge page filesystem mount. +The @option{share} boolean option determines whether the memory +region is marked as private to QEMU, or shared.
