    • Assicurarsi che nel file /etc/qpidd.conf sia settato auth=no .
 
    • use the openstack-config package to turn off force DHCP releases: sudo openstack-config --set /etc/nova/nova.conf DEFAULT force_dhcp_release False (Non viene mostrato nessun output ma modificato il file di configurazione.)
    • If you intend to use guest images that don't have a single partition, then allow libguestfs to inspect the image so that files can be injected, by setting: sudo openstack-config --set /etc/nova/nova.conf DEFAULT libvirt_inject_partition -1 (Non viene mostrato nessun output ma modificato il file di configurazione.)
