Hi,

I have a VE with all the limits cranked up to the max as the only VE
on the host. OVZ is really used only to simplify the administration.

if i look at the output of free(1) on he host and VE, I see this:

VE ~ free -m
total used free shared buffers cached
Mem: 7964 7947 17 0 0 0
-/+ buffers/cache: 7947 17
Swap: 0 0 0

HOST ~ free -m
total used free shared buffers cached
Mem: 7964 7362 602 0 135 3715
-/+ buffers/cache: 3510 4454
Swap: 0 0 0


OK, I understand that VE doesn't know about buffers and caches, but
what puzzles me is the 'free' column. How did it come up with 17 megs?
Does it mean anything or shall I discard all VE OS memory reporting
completely and rely only on the beancounters?
