19.3.1. Applying Boot Options to Guest Virtual Machines
Using virt-manager you can select how the guest virtual machine will act on boot. The boot options will not take effect until the guest virtual machine reboots. You can either power down the virtual machine before making any changes, or you can reboot the machine afterwards. If you do not do either of these options, the changes will happen the next time the guest reboots.
Procedure 19.1. Configuring boot options

19.3.3. USB Redirection
USB re-direction is best used in cases where there is a host physical machine that is running in a data center. The user connects to his/her guest virtual machine from a local machine or thin client. On this local machine there is a SPICE client. The user can attach any USB device to the thin client and the SPICE client will redirect the device to the host physical machine on the data center so it can be used by the VM that is running on the thin client.
Procedure 19.3. Redirecting USB devices
- Open the guest virtual machine's Virtual Machine Details screen.
- Click
