This procedure only mentions how to edit XML saving state that is created by virsh save command. I think it is not common situation because we often edit normal XML file by edit command instead of save-image-edit. This procedure makes us confused since it says like we must create XML saving state by save command first and edit the file by save-image-edit. If we don't have the XML saving state the procedure can be like below. 1. Gether information 2. shutdown the guest image 3. Open the XML file for editing # virsh edit guestVM.xml (optional: if you have XML saving state created by save command) # virsh save-image-edit guestVM.xml --running 4. edit the XML file 5. restart the guest virtual machine Reported by: rhn-support-ryasuoka https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-pci_devices-pci_passthrough#annotations:91f8f39c-8585-41fb-aa44-6b044aca3e52
