7.21. VBoxManage bandwidthctl

This command creates, deletes, modifies, and shows bandwidth groups of the given virtual machine.

VBoxManage bandwidthctl    <uuid|vmname>
                           add <name> --type disk|network --limit <MBps>[k|m|g|K|M|G] |
                           set <name> --limit <MBps>[k|m|g|K|M|G] |
                           remove <name> |
                           list [--machinereadable]

The following subcommands are available:

  • add: Creates a new bandwidth group of a given type.

  • set: Modifies the limit for an existing bandwidth group.

  • remove: Deletes a bandwidth group.

  • list: Shows all bandwidth groups defined for the given VM. Use the --machinereadable option to produce the same output, but in machine readable format. This is of the form: name="value" on a line by line basis.

The parameters are as follows:


The VM UUID or VM Name. Mandatory.


Name of the bandwidth group. Mandatory.


Type of the bandwidth group. Mandatory. Two types are supported: disk and network. See Section 5.8, “Limiting Bandwidth for Disk Images” or Section 6.10, “Limiting Bandwidth for Network Input/Output” for the description of a particular type.


Specifies the limit for the given bandwidth group. This can be changed while the VM is running. The default unit is megabytes per second. The unit can be changed by specifying one of the following suffixes: k for kilobits per second, m for megabits per second, g for gigabits per second, K for kilobytes per second, M for megabytes per second, G for gigabytes per second.


The network bandwidth limits apply only to the traffic being sent by virtual machines. The traffic being received by VMs is unlimited.


To remove a bandwidth group it must not be referenced by any disks or adapters in the running VM.
