nova-volume novaglance nova enabled XXX None<br><br>So, am I missing some package which provides LibvirtDriver class? Or something else could prevent nova-compute to start? I did a lot of googling and I found the same question on several mailing lists and IRC chat logs, but no one gave any solution. <br>
<br>I was hoping that changed over time and that someone could help me with this one.<br><br>Thank you all in advance.<br><br>Best regards.<br><br>
