nova_libvirtd and nova_compute can't auth

I'm trying to deploy openstack into a virtual machine with kolla-ansible (all-in-one mode).

I do all the steps recommended in the docs and still nova-compute refuses to start (and halts the 'deploy' kolla action):

$ kolla-ansible -i all-in-one bootstrap-servers
$ kolla-ansible -i all-in-one prechecks
$ kolla-ansible -i all-in-one deploy
[.. fails, nova-compute not starting ..]

$ grep -v ^# /etc/kolla/globals.yml | grep -v ^$

workaround_ansible_issue_8743: yes
kolla_base_distro: "debian"
kolla_internal_vip_address: "172.16.2.57"
network_interface: "ens3"
neutron_external_interface: "dummy1"
enable_haproxy: "no"
nova_compute_virt_type: "qemu"

Inspection of the nova-compute container logs yields:
