AW: AW: Storage Performance Windows VM
Thanks to all. Disk performance is much better now. I'm wondering why it's different with Ceph. Changing the template will affect new machines only. Existing machines can get changed as well. But the edit button is visible if VM is powered off. Changing my existing machine to virtio ended in BSOD. I'm doing a fresh install now. Thanks again. -Ursprüngliche Nachricht- Von: Gerolamo Valcamonica [mailto:cloudst...@overweb.it] Gesendet: Mittwoch, 17.

Ok, thanks. It's at the template. But changes there will effect new systems only. How do I change my existing once?
