| 85 | <para>
|
|---|
| 86 | The <command>VBoxManage bandwidthctl</command> command enables you
|
|---|
| 87 | to manage bandwidth groups for virtual machines (VMs). A bandwidth
|
|---|
| 88 | group specifies the bandwidth limit for the disks or for the
|
|---|
| 89 | network adapters of a VM.
|
|---|
| 90 | </para>
|
|---|
| 91 | <para>
|
|---|
| 92 | Note that a network bandwidth limit applies only to the outbound
|
|---|
| 93 | traffic from the VM. The inbound traffic is unlimited.
