  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.

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

  @jedimarcus Network configuration (IP, subnet, gateway) only works for Windows guests because there is proper support for it in XenServer Guest Tools for Windows. There is no such support (as far as I know) in XenServer Guest Tools for *nix based systems. Unlike tools for Windows, tools for *nix based systems only contain a few xenstore tools and a daemon (xe-daemon) that collects OS metrics. There is no management agent. My idea is to write a proper agent for *nix based systems at some point but it won't be any time soon. Maybe Citrix (or Vates ?) will implement one before I do. For now, you can use custom based network configuration trough xenstore and custom scripts. It's described in Notes section of the module documentation.

  @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.

  2TiB limit: no. VHD format is limited by design to 2TiB. SMAPIv3 is not yet production ready (qcow2 format is used, without 2TiB limit). We are working on it to get all new SRs available on it, so… patience Also be careful when you want to use very large disk in your VMs, this tends to get your VM less agile (longer migrate time, longer backup/recovery time) No danger. XCP-ng is based on the open source packages of XenServer. No chance Xen or XAPI will be closed in the future, because they are Linux Foundation project. Also, if you didn't, please see this FOSDEM video where I explain the future of XCP-ng project: https://www.youtube.com/watch?v=VpGC5zuLjSs

  @xisco is this XCP thing? or citrix? about pausing VM - this is default behavior in Hyper-V server and is work flawless - restarting server prior to some MS patching - all vm are going nicely to sleep and after boot resumes accordingly.

  I did try that, but it still did not want to recognize and load the PV drivers properly. The VM is still limping with the realtek divers and. It is performing noticeably slow. Oddly others upgraded without a hitch.
