@herhin2017 said: Yes, your wright! I know about that. As i mentioned, our machines are really working perfect (they can easily be a productive system) I am asking because our school does not have much money (in fact nothing) and i will go on with my lessons in hypervisors with xcp-ng. THANKS TO EVERYONE who works on this project - i like it!! P.S. If you need user tests in grater scale, we can do it (10 machines) and we have time. Welcome to the forums! To answer your question while expanding on @Poddingue's excellent point: it all comes down to the AlmaLinux base chosen for the dom0 control domain. While AlmaLinux 10 does offer an alternative x86_64-v2 compilation option for older processors, relying on a sub-baseline build for a modern hypervisor can limit your performance and future third-party repository support. To truly get the most out of XCP-ng 9.0 when it reaches stable release—and to avoid the hard limitations of the modern EFI and Secure Boot requirements—you will want to target at least generation 9 of HPE servers (Gen9) at a minimum. Since you are dealing with a tight school budget but need to acquire a large number of machines for your network engineering students, here are the most effective ways to source that volume: • Corporate Hardware Donations: Depending on your school's official legal status (such as Gemeinnützigkeit), you might be able to get these machines donated for free. Many large companies in Austria cycle out their enterprise hardware every few years and actively look to donate working Gen9 or Gen10 servers to schools for tax benefits or community goodwill. It is highly worth reaching out to local IT departments or tech companies! • Professionally Refurbished Bulk Batches: Sourcing former enterprise hardware in large, uniform batches is your next best path. Gen9 servers offer excellent performance for a very low price right now. Keeping the hardware identical also makes managing your pool templates significantly easier. • Academic Programs & Vates Discounts: If your rollout scales up and you eventually need official commercial backing, it is well worth reaching out directly to Vates. Let them know you are an educational institution; they are often very supportive of academia and may offer steep volume or academic purchasing discounts for schools. Good luck setting up the lab for your hypervisor lessons! P.S. A quick, friendly tip for your English writing: drop the "w" when you want to agree with someone. If you use "write", it sounds like the action of writing words down on paper (schreiben). To agree with someone, the correct phrases are "You're right" or "You are right" (Du hast recht / Sie haben recht).
