<p>MaymeOvermyer: /* Overriding default units */</p> <hr /> <div>{{UBC toc}}<br /> <br /> <br /> # entries which name has word 'page' are measured in [[memory page]]s (4K on x86 and x86_64, 16K for IA64). These are &lt;code&gt;privvmpages&lt;/code&gt;, &lt;code&gt;oomguarpages&lt;/code&gt; and others.<br /> # entries with names like 'num*' are measured in items. i.e. &lt;code&gt;numproc&lt;/code&gt; - number of processes, &lt;code&gt;numiptent&lt;/code&gt; - number of iptables entries.<br /> # other entries like &lt;code&gt;kmemsize&lt;/code&gt;, &lt;code&gt;tcprcvbuf&lt;/code&gt;, &lt;code&gt;tcpsndbuf&lt;/code&gt; are measured in bytes <br /> <br /> == Overriding default units ==<br /> <br /> When using [[vzctl]] to set beancounter parameters, you can set units explicitly when appropriate (i.e. for all parameters which names are not starting with &lt;code&gt;num&lt;/code&gt;*). The following suffixes are available:<br /> <br /> {| class=&quot;wikitable&quot;<br /> | g, G || gigabytes<br /> |-<br /> | m, M || megabytes<br /> |-<br /> | k, K || kilobytes<br /> |-<br /> | p, P || [[memory page]]s<br /> |} <br /> === Examples of [http://www.essaywriters.net/ freelance writing] ===<br /> <br /> * Set kmemsize limit to 512 Kb<br /> &lt;pre&gt;<br /> # vzctl set $CTID --kmemsize 512k<br /> &lt;/pre&gt;<br /> <br /> * Set privvmpages limit to 256 Mb<br /> &lt;pre&gt;<br /> # vzctl set $CTID --privvmpages 256m<br /> &lt;/pre&gt;<br /> <br /> * Set tcprcvbuf limit to 1000 pages (totals to almost 4 Mb on x86)<br /> &lt;pre&gt;<br /> # vzctl set $CTID --tcprcvbuf 1000p<br /> &lt;/pre&gt;<br /> <br /> [[Category: HOWTO]]</div>
