The next step is determining which hypervisor you are connecting to by default: virsh uri If that isn't right (for example, if it returns qemu:///system), then you need to modify how you are calling virt-install to pass an explicit URI (or set LIBVIRT_DEFAULT_URI in your environment). Try 'virt-install -c xen:///' to force libvirt to talk to the xen hypervisor. <a href="http://libvirt.org/uri.html" target="_blank">http://libvirt.org/uri.html</a> gives more details on setting a URI. -- 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> The issue hasn't been eliminated.
