I'm getting more and more confused 
Executing 'free -m' in all containers..
HN# for i in 103 105 106 107; do vzctl exec $i "free -m"; done
vid total used free shared buffers cached
103: 4000 2797 1202 0 0 0
105: 1536 839 696 0 0 0
106: 1536 416 1119 0 0 0
107: 12000 8480 3519 0 0 0
------------------------------------------------
12532
*Note: I cut some irrelevant information for better view
Comparing with executing free in the HN...
HN# free -m
total used free shared buffers cached
Mem: 12008 8299 3708 0 288 4231
-/+ buffers/cache: 3779 8229
Swap: 8575 0 8575
How is possible that the container with vid 107 have more memory (8480MB) than the reported by command free in the HN (8299MB)? (Note: swap usage=0)
vzmemcheck reports something similar:
# vzmemcheck -vA

*Note: I cut some irrelevant information for better view
HN# free -m

The total memory used by containers (without caches) (5247.26MB) are higher than the total system memory (without caches) (3835MB).
What am I missing?
I appreciate any comment!
Thanks!
