Since vzctl 4.6, if some optional beancounters are not set, vzctl sets them implicitly,

The following formulae are used:

<math>vmguarpages_{bar} = vmguarpages_{lim} = ram + swap</math>

: <math>privvmpages_{bar} = privvmpages_{lim} = (ram + swap) \times vm\_overcommit</math>

: <math>privvmpages_{bar} = privvmpages_{lim} = \infty</math>
