[Users] memory reporting in VE

[Aleksandar Ivanisevic]

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?
