<title>Description</title>
<para>
The <command>VBoxManage bandwidthctl</command> command enables you
to manage bandwidth groups for virtual machines (VMs). A bandwidth
group specifies the bandwidth limit for the disks or for the
network adapters of a VM.
</para>
<para>
Note that a network bandwidth limit applies only to the outbound
traffic from the VM. The inbound traffic is unlimited.
</para>
<refsect2 id="vboxmanage-bandwidthctl-add">
<title>Create a Bandwidth Group</title>
<remark role="help-copy-synopsis"/>
<para>
The <command>VBoxManage bandwidthctl add</command> command
creates a bandwidth group for the specified VM. You must specify
whether the bandwidth group is for disks or for networks, and
specify the bandwidth limit.
</para>

<para>
The following example shows how to use the <command>VBoxManage
bandwidthctl</command> command to create the
<literal>Limit</literal> bandwidth group and set the limit to 20
Mbps. Then use the <command>VBoxManage modifyvm</command> command
to assign this bandwidth group to the first and second adapters of
the <literal>vm1</literal> VM.
</para>
<screen>$ VBoxManage bandwidthctl "vm1" add Limit --type network --limit 20m
$ VBoxManage modifyvm "vm1" --nicbandwidthgroup1 Limit
$ VBoxManage modifyvm "vm1" --nicbandwidthgroup2 Limit</screen>
<para>
You can dynamically modify the limit of a bandwidth group while
the VM is running. The following example shows how to modify the
limit for the <literal>Limit</literal> bandwidth group from 20
Mbps to 100 kbps:
</para>
<screen>$ VBoxManage bandwidthctl "vm1" set Limit --limit 100k</screen>
<para>
The following command disables shaping for all adapters in the
<literal>Limit</literal> bandwidth group by specifying a limit of
zero (<literal>0</literal>):
</para>
<screen>$ VBoxManage bandwidthctl "vm1" set Limit --limit 0</screen>
