When run as root, virsh connects to the system libvirt daemon by default (URI
qemu:///system). As a non-privileged user, qemu:///session is used and the
daemon is run as the user.

See http://libvirt.org/uri.html#URI_qemu

You need to run the daemon as root if you want it to listen on
/var/run/libvirt/libvirt-sock

Do you have the develompent headers for readline installed?
