17.5. Editing USB Filters with the USB Filter Editor
17.5.1. Installing the USB Filter Editor
Summary
The USB Filter Editor is a Windows tool used to configure the usbfilter.txt policy file. The policy rules defined in this file allow or deny the pass-through of specific USB devices from client machines to virtual machines managed using the Red Hat Enterprise Virtualization Manager. The policy file resides on the Red Hat Enterprise Virtualization Manager in the following location:
/etc/ovirt-engine/usbfilter.txt
Changes to USB filter policies do not take effect unless the
ovirt-engine service on the Red Hat Enterprise Virtualization Manager server is restarted.
Download the
USBFilterEditor.msi file from the Red Hat Enterprise Virtualization Manager (v.3.3 x86_64) channel of the Red Hat Network.
Note
See the Red Hat Enterprise Virtualization Manager Release Notes for specific channel names current to your system.

USBFilterEditor.msiinstaller obtained from Red Hat Network. - Follow the steps of the installation wizard. Unless otherwise specified, the USB Filter Editor will be installed by default in either

Important
Use a Secure Copy (SCP) client to import and export filter policies from the Red Hat Enterprise Virtualization Manager. A Secure Copy tool for Windows machines is WinSCP (http://winscp.net).
