Hi Igor,<div><br></div><div>Are you running this on Precise? If so, Precise is a bit pickier than previous versions about requiring a setting in /etc/libvirt/qemu.conf</div><div><br></div><div>You need to add /dev/net/tun to the cgroup_device_acl list in that file, and restart libvirt. </div>
<div><br></div><div>This is actually handled automatically by a branch I've pushed for review in devstack: <a href="https://review.openstack.org/#/c/7001/" target="_blank">https://review.openstack.org/#/c/7001/</a></div>
<div><br></div>
<div>It has lots of positive reviews, but still needs one more core review and I've been waiting a while. If you're a devstack core, please give me a hand! :) </div><div><br></div><div>Dan</div><div><br></div><div>
p.s. the root cause of needing to tweak /etc/libvirt/qemu.conf is that we're using libvirt <interface type=ethernet> elements to work with openvswitch. Starting in libvirt 0.9.11 (not available in precise), openvswitch is integrated directly with libvirt, meaning that using type=ethernet (and the workaround) is no longer necessary. </div>

Hello all from sunny Kiev))<br>
<br>
I have built nova+quantum+openvswitch without nova-volume lab on two<br>
nodes - one controller with everything on it except nova-compute and<br>
second dedicated compute node with nova-compute:<br>
<br>
During creating VM I have error which I still can't fix:<br>
$ nova boot --image precise --flavor m1.tiny my-precise-vm3<br>
$ nova list<br>
