[libvirt-users] [libvirt]configuration question about usinf for [xen4.5][libxl]

What configuration should be set in a custom compiled libvirt to get the most out of the xen libxl? [ -f Makefile ] || ./configure --prefix=/usr --libexec=/usr/lib/"$pkgname" --sbindir=/usr/bin \ --with-storage-lvm=yes --with-udev=yes --without-hal --disable-static \ --with-init-script=systemd --with-systemctl=yes --with-systemd-daemon=yes \ --with-qemu-user=nobody --with-qemu-group=nobody \ --without-netcf --with-interface --with-lxc --with-storage-iscsi \ --with-xen=yes --with-libxl=yes # --with-audit After compiling what needs done to configure libvirt to work with xen libxl because all I seem to be getting is: error: failed to connect to the hypervisorerror: no connection driver available for //libxl[dragon@archxen ~]$
