Now i want to install libvirt0.9.7.tar.gz , and i uninstall libvirt0.9.3 and uninstall libvirt0.8.7 with "rpm -e" , i also delete some files contains vesion number 0.8.7 or o.9.3. Today i install libvirt 0.9.7 , untar and install wit "./configure --prefix-/usr/local/libvirt --with-esx", then " make" "make install" ,and i make a link "ln -s /usr/local/libvirt/bin/virsh /usr/bin/virsh" , so i can use virsh . But i cannot start libvirtd ,when i use "service libvirtd start/status.." ,it returns "libvirtd:unrecognized service". I found a libvirtd file in /usr/sbin/.
