You're welcome have you also thought about having a chat with CAD vendor's team? Maybe they encountered it as a problem, as it's more about the CAD and less about having Windows VMs on OpenStack By the way, when a conversation is in a list, reply to all to include the list ;) Best regards Francesco Di Nucci On 13/05/24 12:20, Arne Wiebalck wrote:
Thanks, Francesco!
Licenses are a concern and we're looking at that.
What we're not really clear on if this approach works latency- / concurrency wise. We will probably simply try :)
Thanks again! Arne

Hi,
former CAD user here - first of all I'd advice to clear with your legal department if your license allows you to use the CAD in VMs.
AFAIK CATIA runs on Windows, so containerization is not possible unless you manage to get the CAD running in Wine, and you should configure PCI passthrough
(https://docs.openstack.org/nova/2024.1/admin/pci-passthrough.html) to use a graphic card in the VMs.

Dear all,
We're looking into integrating the use case of CAD applications, such as CATIA V5/6 or CATIA 3DEXPERIENCE, into our OpenStack deployment, with the goals of increased resource sharing and to reduce the park of individual workstations we have for this at the moment.
If anyone has experience running such applications on top of OpenStack (on individual VMs with GPU access, on bare metal servers with concurrent sessions, maybe even containerised ...) and would like to share what they have done, it'd be great if you got in touch with me.
Thanks! Arne
