No. Will fix.
= is requied for <id>

I would like more info in the logfile and a more quiet console.
To do that it is necessary to set LOG_LEVEL to 1 and then use --verbose=0
each time I invoke vzctl.
I think it is more complex :-)

I think level 0 is used for "debug" today.
When starting a VE using LOG_LEVEL=0, I get 10 lines of output.
I think "Running VE script: /etc/vz/dists/..." is debug.

The only(?) way I see to make level 0 more quiet is to raise "noise" [0]
to level 1 (and "Running VE script: ..." to level 2).
If LOG_LEVEL is raised to 1 the output should be the same as today level 0.
(Except "Running VE script: ...")

--quiet is to quiet.

[0] "Noise" when starting VE using level 0:
  Setting CPU limit: 50
  Setting CPU units: 1000
  Configure meminfo: 10240
  2 * "Running VE script: /etc/vz/dists/..."

No, only if "noise" is moved to level 1.
