I'm coming back to you all to help me with a new problem that I've never had before.

I want to show students how to install Openstack with Kolla-ansible. They will each have a computer (DELL Precison 3660 Tower, 32G RAM, 500G SDD).

Ubuntu is the system, version 22.04.

I want to start with an "all-in-one" installation. So I test my-self first…  I follow these procedure https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html

. everything works with the parameters I choose for my configuration, until the following problem:

What can be the problem ? Where can this come from ? I think the CPU is OK for virtualization. I have no idea, I don't know where this error could come from. Do you have an idea? 

Thanks in advance
