Changes

Ploop image can be resized in both directions (i.e. either shrank or grown). Ploop also supports online/live resize so you don't have to stop a CT to do resize.

vzctl set ''CTID'' --diskspace ''nnn''G --save

Note that

* there is no need to specify two values for diskspace (unlike simfs, there is no soft and hard quota).

* there is no way to limit or change the number of inodes available for a container (i.e. option '''--diskinodes''' is ignored)
