  Great projects have great documentation. Is XCP-ng a great project?

  No you can't that's why as an introduction we warn that you need to make a choice, not mix them. We might be able to make our agent work with Citrix drivers in the future, but for this we need a dev.

  Short answer is that the module is referring to wrong symbol table. Its a lookup table for function interaction between module and kernel. Easy answer is to use this .config file and build full kernel.

  As long there is drivers provided by AMD, I think there's no problem to build them and include them into XCP-ng Maybe the real question is more on AMD side of things.

  Thanks Oliver, Sadly, ATI is being going downhill since AMD bought them over.

  If I understand correctly, the "ISO" you are asking for is for building drivers. I don't intend on creating a specific ISO just for that. Everything is available in yum repositories to build drivers (usually you just need make, gcc and kernel-devel), and there's also a docker image at https://github.com/xcp-ng/xcp-ng-build-env I do prefer Olivier's suggestion, though: going through support, because drivers built for one user through support are made available to other users through our repositories.

  Idea/Dev test: HowTo use GlusterFS as SR on XCP-ng

  @r1 the way the rook-ceph works that you pass raw disk to the Debian host and then it creates the OSD and cluster, I have few issues with this: Adding and removing k8s nodes is just few commands and very quick and zero downtime for apps, but if I am running rook-ceph, I need to rebuild the cluster every time I do that and thats extremely time consuming and extra over head. The size of each VM that is being backed up daily/weekly is also extremely big and consumes a lot of resources and storage space. Instead if you get a xcp-ng native local cluster that can be used by VM's as local block type SR that would simplify the implementation many times.

  @imtrobin No, AMD. Currently a WX4100 (as its LP and fits into a 2U server) but have also had a RX580 working before.

  @peder Thank you. Unfortunately, that machine is in datacenter so dont have physical usb access. Nevertheless, I found a way to do the conversion. Seems as XenConvert 2.3.1 is capable of doing it, however, its only that version that does it, the rest are all different. Therefore, issue resolved for conversion, but i'm still wondering if im the only one that had that issue or is it quite common given the system version I have to xcp and the center.

  @fibrewire If you're looking at a free way to do so, you can install XOA from the sources and do it through that. I honestly don't miss the updates portion of XCP-ng Center (even after having used it for years in XenCenter). It was very clunky and time-consuming; and, I ultimately ended up scripting a lot of it locally on hosts instead. This is obviously much easier now that it can be done through a simple "yum" command instead of having to pull all the separate packages and install them like XenServer does. XOA will obviously provide that feature through the paid versions as well (if you've already got it). I'm not big on pushing people to XOA from XCP-ng Center, as I still use XCP-ng Center way more than XOA (at least until they push out the new version with the tree view so I can give it a try); but, that's the easy answer to your question.

  Hi. Unfortunately, there's no other way than booting from an ISO to install XCP-ng. You can't convert an CentOS into XCP-ng. The disk layout would not be good, and actually "our" OS runs as a Xen domain.

  No, i tried that and its doesnt work for keyboard and mouse even with the usb policy change, my keyboard and mouse shows up in the gui and VMs start fine with no errors but they still control dom0 and not the guests. it does not matter because the topic is actually about pcie passthrough that refuse to passthrough my onboard moterboard usb. i think there is some configuration that citrix has implemented.

  You don't need a link. You can simply attach the guest-tools.iso, already present and known by XCP-ng, to the VM and mount it.

  XCP-ng includes Xen as a core component but it's probably not the only component that is involved. I can't answer to the question about "how much" it differs from someone using Xen directly. Someone would need to investigate that.

  CH 8.1 has the same kernel than 8.0. So by default, will have the same too.
