guest kernel needs 64 bytes of DRAM per 4K page of emulated PMEM, hence the image size should be as small as possible to reduce the container's memory footprint. The image size is recalculated automatically if it's too small to contain the rootfs. Signed-off-by: Julio Montes <julio.montes@intel.com>
