Hi user-mirror, It's not clear for your test environment such as OS platform, libvirt, virt-manager and kvm version, etc. In addition, if you can reproduce the issue again, please attach related logs file as a attachment such as libvirtd.log and virt-manager.log, it will be helpful to narrow debugging time. If you don't know how to generate a customized libvirtd.log, please refer to this link: http://libvirt.org/logging.html For virt-manager logs, it locates in ~/.virt-manager/virt-manager.log.
