Hello Thank you very much for responding quickly but it did not work for me. when doing the second step i got the following error no package ...... available error: nothing to do ----- Mensaje original ----- De: "Strahil" <hunter86_bg(a)yahoo.com&gt; Para: "users" <users(a)ovirt.org&gt;, "Katia Monjes Machado" <katiam(a)softel.cu&gt; Enviados: Viernes, 8 de Marzo 2019 10:39:51 Asunto: Re: [ovirt-users] error failed to execute stage 'misc configuration': failed to start service 'openvswitch' This should work only for EL7 based systems. Find what provides it: yum whatprovides '*/openvswitch.service' Then check if it is installed: rpm -qa <replace with output of previous command> If not, install via 'yum install <replace with output of previous command>' Best Regards, Strahil Nikolov
