Eric. I attached the figure，which showed when I ran the command "virt-manager". I also tested the commad as follows, sa you can see my output.

Your embedded graphic (at least, I'm assuming you attempted to embed a graphic) got eaten by the list server, so we don't know what message you got. Can you paste the actual error message you got? Meanwhile, we have a wiki page for diagnosing common problems. Perhaps your issue is covered by one of the items there; and if not, it would help if you could add a new page with the steps you take in resolving the issue. <a href="http://wiki.libvirt.org/page/Troubleshooting" target="_blank">http://wiki.libvirt.org/page/Troubleshooting</a> <div> > > > Then I did a little test: > I ran the conmand "virsh list" , but it didnot work,either. </div>Again, knowing the exact output of 'virsh -c qemu:///system list', rather than just saying it didn't work, will help others in diagnosing your issue. -- Eric Blake <a href="mailto:eblake@redhat.com" target="_blank">eblake@redhat.com</a> +1-919-301-3266 Libvirt virtualization library <a href="http://libvirt.org" target="_blank">http://libvirt.org</a> </blockquote></div> </div></div></div>
