  1. Great article and thanks for getting the awareness of both products out there. Would have preferred a conclusive choice between the two, but nonetheless, great article.

  2. Amigo, diferente do que diz seu artigo, o Proxmox faz a virtualização de GPU com ferramenta disponível na aplicação, porém tem de ser habilitada.

  3. Wait, no GPU virtualization out-of-the-box? I thought Proxmox, at least, had that already. Are we talking passthrough or are we talking SR-IOV?

    1. Yes. Proxmox has SR-IOV support, I’m using it to passthrough virtual function of a NIC to guests.
      So if the GPU support SR-IOV I don’t see why it wouldn’t work and I think I already saw some videos demonstrating that feature.

  4. Additionally, while XCP-ng and Proxmox VE offer web interfaces for managing VMs and clusters, they lack some advanced management features in commercial virtualization platforms like VMware’s vSphere.

    Both platforms support local storage, NFS, and iSCSI, but neither has native support for object storage solutions, such as Amazon S3 or OpenStack Swift.

    Neither does vSphere, so I’m not sure why this is even brought up.

  5. I’ve used both but the ability to run LXC containers in Proxmox is what makes it my choice. All the servers in my lab are LXC containers, including my Plex server. And I can still expose the GPU to it in order to do hardware transcoding.

  6. I’m a long time user of Proxmox, there are a lot of advantages while using it mainly due the fact it’s based on Debian.

    The thing is that I recently switched to XCP-NG because of the backup solution and other things such as the simplicity that these guys handle things and I was playing around with Proxmox just to acheive the basic functionalities which was build-in.
    I still can’t create a proper vGPU on XCP-NG and thin-clients solutions as I have with my Proxmox
    cluster, but the it fail me one time and it’s enough for me – couldn’t start a machine due to lack of quorum !!!

    1. Lior,

      Thank you for your comment and insights into using both. I haven’t tried vGPU passthrough on XCP-ng but I need to play around with this for sure.
