Open Stack

Hi all,

I'm trying to deploy DevStack inside an Ubuntu Server 20.04.3 LTS virtual machine inside VirtualBox, but I'm struggling a lot, I got a lot of different errors.

My use case: I want to test Zuul and DevStack, so I'll create a virtual machine for DevStack and one for Zuul, both on VirtualBox. I'm using a Host-only adapter with CIDR 192.168.200.0/24, and I need DevStack to be accessible on this network, and to use this network as the floating range for giving floating IP addresses to instances inside DevStack, so that Zuul can also access them.

My local.conf: https://paste.openstack.org/show/809182/
Screenshots of the network configuration of my VirtualBox VM:
First adapter, NAT (used for internet connectivity): https://i.imgur.com/C7XTiLJ.png
Second adapter, host-only, used for communication with my Windows host and other VMs in the same network: https://i.imgur.com/Qeciuqx.png

DevStack is erroring with the arping command on lib/neutron-legacy, arping gets 0 responses and exits the script with exit code 1

Does anyone have experience in dpeloying DevStack inside VirtualBox in such manner? I really need some help with this, if anyone could give me some ideas of waht could be wrong, it'd very much appreciated! Thanks.
