VZ users-
Can someone explain to me how vzcalc calculates the current and max
Mem? I initially thought Promised% was based upon VMGUAR and Max% was
based upon PRIVVM, but that doesn't seem to be the case. I believe I'm
allowing 128MB of guaranteed mem and 512MB burstable using the
parameters below. Is that true? The HN below has 32GB ram 64GB swap.

$  /etc/vz/conf/3166.conf

$ vzcalc -v 3166
Resource     Current(%)  Promised(%)  Max(%)
Low Mem          0.04       0.53       0.53
Total RAM        0.10        n/a        n/a
Mem + Swap       0.03       0.20        n/a
Alloc. Mem       0.05       0.20       0.68
Num. Proc        0.00        n/a       0.15
Memory           0.10       0.53       0.68

Thank You for the great software! It has dramatically improved the way we work.
