Hey mogliii, Than you very much. It worked. I first did on the controller node: $ apt-get upgrade
And then on every compute node: $ sudo service virtlogd restart * Restarting libvirt logging daemon /usr/sbin/virtlogd $ sudo service libvirt-bin restart libvirt-bin stop/waiting libvirt-bin start/running, process 3586 Check: $ ps -ef | grep libvirt root 3586 1 0 13:14 ? 00:00:00 /usr/sbin/libvirtd -d $ ps -ef | grep virtlogd root 3523 1 0 13:13 ? 00:00:00 /usr/sbin/virtlogd -d That worked for me and I could create a VM with: $ openstack server create .... Since it is a workaround, has anybody an idea what the permanent solution would be?
