I've deployed an all in one Openstack on Centos 8 stream using kolla-ansible following the tutorial in openstack kolla website. After the deployment, I used the int-runonce script to create networks and stuff, but after launching a cirros VM, I found that the network interfaces inside the VM didn't get IP addresses from the neutron DHCP agent, therefore that instance was not reachable from nowhere. The docker container of the dhcp agent is up and running, but VMs don't receive any data from it.

which network did you use. the default external network that is created has dhcp disabled. https://github.com/openstack/kolla-ansible/blob/master/tools/init-runonce#L8... so if you used the public1 network they will not recive dhcp adresses in the vms.
