Hi list,

I found the cause for the ( Error  unsupported configuration: Emulator '/usr/bin/qemu-system-x86_64' does not support virt type 'kvm'),   I  missed the qemu/kvm enabling in the /etc/kolla/globals.yml

nova_compute_virt_type: "qemu"     // once I added this and  done a  reconfigure  it works. ( kvm I didn't try  not sure whether need to add some special parameter enabling needed for nested virtualization scenario as in my case My host VM,  which is ubuntu22.04 ) 

(kolla_ansible_venv2) ubuntu@ubuntu-VM:~$ kolla-ansible -i all-in-one reconfigure


I am posting this here for beginners like me who are just exploring OpenStack for adopting/advising  the stack for large scale implementation especially in the government sector.

1. I followed the tutorial 


https://kifarunix.com/deploy-all-in-one-openstack-with-kolla-ansible-on-ubuntu-22-04/?expand_article=1

and able to get things up and running upto  horizon dashboard login.( with the runinit once script ) which brings the default cirros image and default flavors and default networks.


2. When I tried to  create a cirros instance either through the horizon dashboard or through openstack CLI  the instance not up and running resulting in error . 


3. NOTE: This   kolla-ansible-all-in-one I am trying on a VM(   Ubuntu22.04  VM deployed on  ESXi 7.0 host).  

4. Do I need to edit or enable something on the ESXi host machine or the  Ubuntu base  VM  where I am trying the all-in-one installation ?
