address@hidden ivshmem and hugepages
+
+Instead of specifying the <shm size> using POSIX shm, you may specify
+a memory backend that has hugepage support:
+
address@hidden
+qemu-system-i386 -object
memory-backend-file,size=1G,mem-path=/mnt/hugepages,id=mb1
+ -device ivshmem,memdev=mb1
address@hidden example
+
+ivshmem-server also supports hugepages mount points with the
address@hidden memory path argument.
