But there are not such services: libvirtd-tcp.socket libvirtd-tls.socket I really not understand how to enable them.:) Should I reinstall libvirtd on my Ubuntu OS, or should I only need install the missing packages about the two services ?

On my machine: $ systemctl list-unit-files | grep libvirt libvirt-guests.service enabled enabled libvirtd.service enabled enabled libvirtd-admin.socket enabled enabled libvirtd-ro.socket enabled enabled libvirtd-tcp.socket disabled enabled libvirtd-tls.socket disabled enabled libvirtd.socket enabled enabled This is Debian, but the Ubuntu package is pretty much identical, so I don't expect it to behave differently. So the unit exists on you system, you just need to enable it :) -- Andrea Bolognani / Red Hat / Virtualization
