Good. 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.
http://libvirt.org/uri.html gives more details on setting a URI.
