Hi,
In short - you can.
Some deployment tools, like OpenStack-Ansible or kolla-ansible provide guides for all on one deployments. Devstack also is capable of that, since this principal is widely used in our CI, as tempest scenarios usually spawn real VMs and CI is run inside openstack VMs as well.
This usually involve creation of dummy interfaces, that are used in bridges as tunnel ones and then instaces are connected to these bridges through neutron.
So here you can find some docs and architecture involved:
Hello,
Could I deploy openstack in openstack instance?
When I use a instance just with one network interface. After ip move to brq(using linuxbridge) or br-ex(uring openvswitch), the instance lost connection.
Does anyone know how to set it up? Or suggest me some documentation.
I would appreciate any kind of guidance or help.
Thank you.
