This is a subject of bug #2592 (and a number of its duplicates):
https://bugzilla.openvz.org/2952

Thanks, thought as much, but can't really google it since the error in
that bug report is worded differently.

This message is harmless (although it's a slight hint you might want
Yeah, we really appreciate slight hints that break half of the scripts
we scripted around vzlist, but I guess you get what you paid for ;)

I thought this message is printed to stderr not stdout. Or am I wrong?

I took a tea break to check it myself, because if it is the way you reported it is,
the bug is much more severe than I thought.

Here are the results:

[root@ce6 ~]# vzlist -a -o ctid,layout
Can't load ploop library: libploop.so: cannot open shared object file: No such file or directory
Please install ploop packages!
      CTID LAYOUT
       101 simfs
       102 ploop

[root@ce6 ~]# vzlist -a -o ctid,layout 2>/dev/null
      CTID LAYOUT
       101 simfs
       102 ploop

(checked with json output as well, same results -- errors go to stderr)

So, unless you are doing something like 2>&1 when calling vzlist, this bug
is not affecting you, thus not "breaking half of the scripts". If you do 2>&1,
this is the wrong thing to do and you should fix (half of?) your scripts.

Nevertheless, I will fix it in 4.7.1 (not sure about the timing though).
Sorry for the trouble.
