What does virsh --version=long say? Also, are you sure libvirtd is running? -- Eric Blake <a href="mailto:eblake@redhat.com">eblake@redhat.com</a> <a href="tel:%2B1-919-301-3266" value="+19193013266">+1-919-301-3266</a> Libvirt virtualization library <a href="http://libvirt.org" target="_blank">http://libvirt.org</a> </blockquote></div> Eric, Here is the output: # virsh --version=long Virsh command line tool of libvirt 0.9.10 See web site at <a href="http://libvirt.org/">http://libvirt.org/</a> Compiled with support for: Hypervisors: Xen QEmu/KVM UML OpenVZ VirtualBox LXC Test Networking: Remote Daemon Network Bridging Nwfilter VirtualPort Storage: Dir Filesystem SCSI Multipath iSCSI LVM Miscellaneous: SELinux Secrets Debug It seems that it does support Xen. I am not sure if libvirtd is running so I use the following command to start it: [root@XenTester srv]# /etc/rc.d/init.d/libvirtd start But the same error is still there. Am I using the right way to start libvirtd service? Are there any other possible reasons of this error? Thanks, -- Su Zhang Ph.D Candidate Computing and Information Sciences Kansas State University
