This is helpful to catch fragmenting guest physical memory in strange fashions. Right now we can crash QEMU by e.g. (there might be easier examples) qemu-system-x86_64 -m 256M,maxmem=20G,slots=2 \ -object memory-backend-file,id=mem0,size=8192M,mem-path=/dev/zero,align=8192M \ -device pc-dimm,id=dimm1,memdev=mem0 Signed-off-by: David Hildenbrand <david@redhat.com> Message-Id: <20180607154705.6316-2-david@redhat.com> Reviewed-by: Michael S.
