15.6. Removing USB devices from virtual machines by using the command line

Procedure

1. Locate the bus and device values of the USB that you want to remove from the VM.

   For example, the following command displays a list of USB devices attached to the host. The device we will use in this example is attached on bus 001 as device 005.

   # lsusb
   [...]
   Bus 001 Device 003: ID 2567:0a2b Intel Corp.
   Bus 001 Device 005: ID 0407:6252 Kingston River 2.0
   [...]

2. Use the virt-xml utility along with the --remove-device argument.

   For example, the following command removes a USB flash drive, attached to the host as device 005 on bus 001, from the example-VM-1 VM.

   # virt-xml example-VM-1 --remove-device --hostdev 001.005
   Domain 'example-VM-1' defined successfully.

   To remove a USB device from a running VM, add the --update argument to this command.
