Trying to set up a Stein cloud with Packstack. I want the Openvswitch mech driver and VXLAN type driver. A few weeks ago, the following invocation was successful:

sudo packstack --debug --allinone --default-password pw        \
               --os-neutron-ovs-bridge-interfaces=br-ex:eth0   \
               --os-neutron-ml2-tenant-network-types=vxlan     \
               --os-neutron-ml2-mechanism-drivers=openvswitch  \
               --os-neutron-ml2-type-drivers=vxlan,flat        \
               --os-neutron-l2-agent=openvswitch               \
               --provision-demo-floatrange=10.1.1.0/24         \
               --provision-demo-allocation-pools '["start=10.1.1.10,end=10.1.1.50"]' \
               --os-heat-install=y --os-heat-cfn-install=y

Now, it fails during network setup. My network connection to the Packstack server is severed, and it turns out that its only network interface eth0 has no IP address and is down. No bridge exists.

In the network.pp.finished file, I find various ovs-vsctl commands including add-br, and a command ifdown eth0 which fails with exit code 1 (no error message from the ifdown command is logged).

Can somebody recommend the options required to successfully deploy a Stein cloud based on the Openvswitch and VXLAN drivers?

Thanks much,

Bernd
