I just created a 2 and also

in the next run a 3 node (multinode) deployment

using kolla-ansible (quick start guide).

I launched an instance using the cirros image.

But now in both deployments I can't connect to

any external networks.

I also tried creating a new external (provider) network manually (after the init-runonce script)

using horizon (Admin->Networks-Create Network)

but I always get the generic error "Error: Failed to create network ..."

I looked online and found it could perhaps have

something to do with a missing driver for neutron

or so (flat, etc.)

But I don't know how I can achieve this in

kolla/kolla-ansible.

Some details about the environment:

2 node deployment:

vmware player

1. vm: control/networking/monitoring node 1xcpu, 4GB memory

2 NICs:

1: NAT,

2: host internal network (tried with nat aswell)

2. vm: compute/storage node

4xcpu, 16GB memory.

2: host internal network (tried with nat aswell)

2 NICs:

1: internal network (routed to wan using router),

2: same internal network

3. vm: same as 1. vm

- Btw the connectivity to the virtual router-nic, etc.

is working, but no external connectivity.

- I also enabled the promiscuous mode

in the vswitch in the esxi host

so that shouldn't be the problem.

- The second interface also doesn't have any ip address, except some link-local ipv6 adresses using autoconfiguration.

- I also tried the 2 node deployment in virtualbox before I tried it in vmware player, but there I got the same results.

Is the default configuration of kolla/kolla-ansible

perhaps missing something

or am I missing some important step

regarding the network configuration

(in e.g. virtualbox, VMware Player or esxi)?
