<li>Increase the values. Say, we want to increase kmemsize by 1.5 2 times. This is how it can be done using built-in bash arithmetics:
<pre>
# vzctl set 123 --kmemsize $((2752512*1.52)):$((2936012*1.52)) --save
</pre>
By using <code>--save</code> flag, we denote we want to both apply the new settings to the running VE, and save them in the configuration file (from which they will be taken during next VE start).
