<section id="project-limits">
<span id="id2"></span><h2>Project limits<a class="headerlink" href="#project-limits" title="Link to this heading">¶</a></h2>
<p>Project limits define a hard upper bound for the resources that can be used by the containers and VMs that belong to a project.</p>
<p>Depending on the <code class="docutils literal notranslate"><span class="pre">limits.*</span></code> option, the limit applies to the number of entities that are allowed in the project (for example, <a class="configref reference internal" href="#project-limits:limits.containers"><code class="docutils literal notranslate"><span class="pre">limits.containers</span></code></a> or <a class="configref reference internal" href="#project-limits:limits.networks"><code class="docutils literal notranslate"><span class="pre">limits.networks</span></code></a>) or to the aggregate value of resource usage for all instances in the project (for example, <a class="configref reference internal" href="#project-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> or <a class="configref reference internal" href="#project-limits:limits.processes"><code class="docutils literal notranslate"><span class="pre">limits.processes</span></code></a>).
In the latter case, the limit usually applies to the <a class="reference internal" href="../instance_options/#instance-options-limits"><span class="std std-ref">Resource limits</span></a> that are configured for each instance (either directly or via a profile), and not to the resources that are actually in use.</p>
<p>For example, if you set the project’s <a class="configref reference internal" href="#project-limits:limits.memory"><code class="docutils literal notranslate"><span class="pre">limits.memory</span></code></a> configuration to <code class="docutils literal notranslate"><span class="pre">50GiB</span></code>, the sum of the individual values of all <a class="configref reference internal" href="../instance_options/#instance-resource-limits:limits.memory"><code class="docutils literal notranslate"><span class="pre">limits.memory</span></code></a> configuration keys defined on the project’s instances will be kept under 50 GiB.</p>
<p>Similarly, setting the project’s <a class="configref reference internal" href="#project-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> configuration key to <code class="docutils literal notranslate"><span class="pre">100</span></code> means that the sum of individual <a class="configref reference internal" href="../instance_options/#instance-resource-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> values will be kept below 100.</p>
<p>When using project limits, the following conditions must be fulfilled:</p>
<ul class="simple">
<li><p>When you set one of the <code class="docutils literal notranslate"><span class="pre">limits.*</span></code> configurations and there is a corresponding configuration for the instance, all instances in the project must have the corresponding configuration defined (either directly or via a profile).
See <a class="reference internal" href="../instance_options/#instance-options-limits"><span class="std std-ref">Resource limits</span></a> for the instance configuration options.</p></li>
<li><p>The <a class="configref reference internal" href="#project-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> configuration cannot be used if <a class="reference internal" href="../instance_options/#instance-options-limits-cpu"><span class="std std-ref">CPU pinning</span></a> is enabled.
This means that to use <a class="configref reference internal" href="#project-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> on a project, the <a class="configref reference internal" href="../instance_options/#instance-resource-limits:limits.cpu"><code class="docutils literal notranslate"><span class="pre">limits.cpu</span></code></a> configuration of each instance in the project must be set to a number of CPUs, not a set or a range of CPUs.</p></li>
<li><p>The <a class="configref reference internal" href="#project-limits:limits.memory"><code class="docutils literal notranslate"><span class="pre">limits.memory</span></code></a> configuration must be set to an absolute value, not a percentage.</p></li>

<p>To prevent the instances of a project from accessing security-sensitive features (such as container nesting or raw LXC configuration), set the <a class="configref reference internal" href="#project-restricted:restricted"><code class="docutils literal notranslate"><span class="pre">restricted</span></code></a> configuration option to <code class="docutils literal notranslate"><span class="pre">true</span></code>.
You can then use the various <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> options to pick individual features that would normally be blocked by <a class="configref reference internal" href="#project-restricted:restricted"><code class="docutils literal notranslate"><span class="pre">restricted</span></code></a> and allow them, so they can be used by the instances of the project.</p>
<p>For example, to restrict a project and block all security-sensitive features, but allow container nesting, enter the following commands:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>lxc project set &lt;project_name&gt; restricted=true
lxc project set &lt;project_name&gt; restricted.containers.nesting=allow
</pre></div>
</div>
<p>Each security-sensitive feature has an associated <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> project configuration option.
If you want to allow the usage of a feature, change the value of its <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> option.
Most <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> configurations are binary switches that can be set to either <code class="docutils literal notranslate"><span class="pre">block</span></code> (the default) or <code class="docutils literal notranslate"><span class="pre">allow</span></code>.
However, some options support other values for more fine-grained control.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>You must set the <code class="docutils literal notranslate"><span class="pre">restricted</span></code> configuration to <code class="docutils literal notranslate"><span class="pre">true</span></code> for any of the <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> options to be effective.
If <code class="docutils literal notranslate"><span class="pre">restricted</span></code> is set to <code class="docutils literal notranslate"><span class="pre">false</span></code>, changing a <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> option has no effect.</p>
<p>Setting all <code class="docutils literal notranslate"><span class="pre">restricted.*</span></code> keys to <code class="docutils literal notranslate"><span class="pre">allow</span></code> is equivalent to setting <code class="docutils literal notranslate"><span class="pre">restricted</span></code> itself to <code class="docutils literal notranslate"><span class="pre">false</span></code>.</p>
