If I boot with -m 512 I get this:
root@(none):~# free
total used free shared buffers cached
Mem: 378608 25196 353412 0 1012 8692
-/+ buffers/cache: 15492 363116
Swap: 0 0 0
so something is definitely eating a lot of memory (missing about 142M).
Same guest kernel/fs in qemu gets:
freeroot@(none):~# free
total used free shared buffers cached
Mem: 407080 23236 383844 0 1056 8692
-/+ buffers/cache: 13488 393592
Swap: 0 0 0
so it's missing about 114M.
