Hi all,

This must be simple to do, but when I try to follow the guide in a vagrant box to run the fullstack suite locally, I am hitting a wall. I suspect I miss something obvious but I can't figure it out.

I'm following this doc: https://docs.openstack.org/neutron/latest/contributor/testing/fullstack.html#how-to-run-fullstack-tests-locally

I start with an empty ubuntu 22.04 vagrant box with enough memory, disk, cpu. Then I check out the neutron repo and devstack into my home dir. I also `mkdir -p /opt/stack/ && chmod a+rwx /opt/stack` and clone `requirements` repo in /opt/stack/requirements. (Otherwise configure_for_func_testing script fails.)

Then I execute:

export VENV=dsvm-fullstack
tools/configure_for_func_testing.sh ~/devstack -i

(I am not sure setting VENV envvar is needed, but that's what is in the doc)

It successfully completes (I see "Phew, we're done!" message from the script.)

I then:

$ tox -e dsvm-fullstack neutron.tests.fullstack.test_logging

(or any other test case that triggers Open vSwitch)

and the test just fails with timeout. And when I look into logs, I see interface additions failing and in vswitchd log:

Aug 21 20:24:26 ubuntu ovs-vswitchd[42747]: ovs|00032|bridge|ERR|failed to create bridge br-eth68909740e: No such file or directory
Aug 21 20:24:26 ubuntu ovs-vswitchd[42747]: ovs|00031|ofproto|ERR|failed to open datapath br-eth68909740e: No such file or directory
Aug 21 20:24:26 ubuntu ovs-vswitchd[42747]: ovs|00030|ofproto_dpif|ERR|failed to open datapath of type system: No such file or directory

(there are more errors of the same...)

I disabled apparmor as the doc suggests. I also confirmed that the `openvswitch` kernel module is loaded (it is not loaded after ovs and ovn are built from source as part of configure_for_func_testing.sh execution). I also tried to run the suite as root. (I don't think this is needed, but I figured I'll check.)

Anyone else running into this? How do you guys execute the suite locally?
