Hello based with these documentation https://docs.openstack.org/mitaka/install-guide-ubuntu/neutron-compute-install.html (https://docs.openstack.org/mitaka/ins...) By neutron is there some more detailed documentation available how to install Mitaka with OpenVSwitch instead Linux-Bridge on Ubuntu 16.04?

You may install Mitaka with OVS by default via any RH's deployment approach :- packstack (yet completely functional) or TripleO on CentOS 7.X.

Configuration, though not installation, is found in the networking guide. For installation, perhaps the Ubuntu wiki helps.

I get it running now. But it seems that works under Debian with KVM only. By switching to XEN i got erroes

can't add tap802da6a9-90 to bridge br-int: Operation not supported

XEN is configured to use openvswitch by self. But something calls the wrong scripts. And if I hack the scipts by myself, then neutron puts the interfaces into the wrong bridge :/

Your choice of hostname betrays deep frustration with technology.

A bit of constructive contribution, perhaps: Did you configure this correctly? "ovsbr1" in the line "Failed to bind..." should be a bridge, not a network.

I've got everything running now. Yes it was a misspelled configuration. But after a while I have understood neutron by the hard way. The names of my computers are all named in rhine-area stile. Like Schlimmwutz or Puppekopp. They is no frustration about technologie. It's just a tradition.
