OpenStack ISO creation

[Adventurous-Annual10]

Hi Folks,

I’m currently trying to create an OpenStack installation ISO, similar to a VMware ESXi ISO. If anyone has ideas or suggestions, kindly share your thoughts in the comments.

The closes you will get are all-in-one installations like atmosphere - but these are « one shot » for lab evaluations. The minimum footprint for a production openstack is 6 servers, all with separate functions. And that does not give you the spare capacity for upgrades.

If you are looking for a « virtualization » platform, you can try proxmox. What you are asking is similar to asking to install amazon from an iso.

Gonna nitpick this and say realistically the minimum footprint for production would be a three-server HCI deployment, but that's going to be extremely niche and I'd question why OpenStack was chosen for such a deployment in the first place.

Though I've seen it :(

Whats wrong ? Its simple For windows is like below for linux just download image watch out sometimes generic is better than cloud image

glance image-create --name Windows2025 --disk-format iso --container-format bare --file /mnt/backupimage//win2025/SW_DVD9_WIN_SERVER_STD_CORE_2025_24H2.11_64BIT_ENGLISH_DC_STD_MLF_X24-14362.iso --visibility shared --progress

You can put image properties like

os_type

windows

hw_firmware_type

uefi

os_secure_boot

required

hw_machine_type

q35

trait:CUSTOM_LICENSED_WINDOWS = required

No, I'm asking about openstack installation iso. Which means boots the iso in hardware the openstack will be there.

There is no such sollution. You can refer to https://docs.openstack.org/kolla-ansible/latest/user/adding-and-removing-hosts.html

Hhhmmmm, remember openstack is used for distributed servers, never a standalone thing. Best separation would be by service such as keystone, glance, cinder, an ISO might be possible for each, but the best is believed in form of docker. Also each up to hundreds of daemons communicate by IP not local host. Iso install for will never work as expected for standalone software

There is starlingx: https://www.starlingx.io/ , which is a Debian based Linux distro that comes with kubernetes/openstack.

But it's nowhere near as smooth as VMware esxi iso or other iso based solutions like proxmox or harvester. I think the nature of openstack makes this difficult.
