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

  @Patrik48 Just to make things clear: there is no documentation (or project of documentation) that would be restricted to those who subscribed to pro support.

  As a starting point, see https://github.com/xcp-ng/xcp/wiki/Logfiles and look for whatever happened by the time of the crashes, if logging was still operational at that moment.

  Well, first you can simply tell which driver and give a link to the upstream sources and we could consider providing it as an alternate driver directly in our repositories for everyone. To build it yourself, there are several solutions: Use this template: https://github.com/xcp-ng-rpms/kernel-driver-template and build your RPM in a docker container that we provide as an alternative to the DDK (more convenient and uses XCP-ng packages). Or use Xenserver's DDK (this solution still works because we're using the same kernel, but we prefer the first one). See also: https://github.com/xcp-ng/xcp/wiki/Kernel-modules-policy

  @bnrstnr said in Storage Link: Can you explain better exactly what you're trying to do? Only for easy mapping of a disk to storage directly to a virtual server. Thus Avoiding the need for iSCSI configuration within the Guest VM. I Know the appeal today is no longer available... My question is whether anyone knows if it is still possible to perform via CLI or if there are plans to be implemented again.

  You are right, this is clearly the future. It's still incomplete but we have hope to get something really great at the medium/long run.

  XCP-ng GPU Passthrough - No GPU found

  Hello, My idea was to passthrough GPU to specific VM. According to many informations from the Internet, I'm doing this like that: /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(03:00.0)(03:00.1)" but still even after reboot I see it on lspci xe vm-param-set other-config:pci=0/0000:03:00.0, 0/0000:03:00.1 uuid=c41704d0-a1f2-6bc1-fe2e-adc26697e636 for old Nvidia 8600 and GT430 it doesn't work - Windows VM see that device, drivers are installed but all the time I have error 43 and this device is stopped for Radeon 7870 it work ok Audio and USB is working with that metod also. Is this connected with Vbios of this GPU's ?

  I agree. Ideally we should also contribute such changes to the xe-guest-agent upstream repository.

  @schories It should be noted here that the emulated BIOS in XCPNG7.6 seemingly doesn't care about the bootflags. If the first one (per device id) isn't bootable it will fail, even if xvdb is bootable! So if you e.g. have swap on xvda, move it to another device id at the end (and temporarily disable it in fstab or so)

  Actually, looks like I had already written something about it in the Updates Howto: https://github.com/xcp-ng/xcp/wiki/Updates-Howto#a-special-word-about-xcp-ng-75-76-and-live-migrations

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

  We got an ext4-ng driver already working. But benchmarks are… not good so far. So now the goal is to investigate to find the bottleneck. Oddly enough, even while using what we thing the same datapath than SMAPIv1 (yes you can do that), it's still slower. In the end, we must really understand exactly how this whole stuff works, so we could improve it ourselves (there is no public master branch for some repo, thanks Citrix…) edit: we are using the datapath coded by Citrix, so they should suffer the same problem than us for GFS2. I don't understand how this could be "production ready", but that's another story.
