    I am running NVIDIA P40s on a DELL R720/R730 and a NVIDIA A2000 12GB on a DELL Optiplex 9010 in my playlab. Getting the GPUs to be accessible for VMs was quite easy: shutdown the XCP-ng host, install the GPUs, start the host again, activate the GPU in the advanced settings of the host in the PCI Devices section (“Passthrough enabled”). The host will restart at this point after displaying a warning. That's it – the GPU can now be assigned to a VM in the VMs advanced settings. I do use the GPUs for AI workloads under Debian though, so your use case might vary.

    @bleader Hopefully the palm print on my forehead isn't visible from where you are sitting. Of course the interface needs an IP address. In my defense, normally for something like this, I wouldn't put it on the bonded interface with all the trunked VLAN's for guest traffic (we don't give that one an IP) and it would go on the other bonded interface that isn't trunked and does get an IP, but these are test hosts and I didn't set up the other bond, so it is pulling double duty. I was able to set the IP's and get SDN working. Thanks!

    Having the flag "Protect from accidental deletion" has since yesterday left me with plenty of restored VMs. In the backup logs, it indicates that this happens during the healthcheck. This has happened on 3 out of 6 VMs Update: The other 3 VMs were opt-out from Healthchecks. So that is why this didn't affect them.

    Kubernetes CCM for Xen Orchestra v1.0.0-rc.1 We’re shipping v1.0.0-rc.1, our first release candidate on the road to a stable 1.0.0! This RC is feature-complete and ready for real-world use. Please try it out and share any feedback—bugs, regressions, or usability notes—so we can polish the final release. Thank you for testing and helping us! https://github.com/vatesfr/xenorchestra-cloud-controller-manager/releases/tag/v1.0.0-rc.1 Golang SDK for Xen Orchestra v1.11.0 SDK v2: VM and Task services now match the latest REST API. Host service has been added for host data retrieval. Integration tests have also been strengthened to boost reliability. The v2 SDK is gradually becoming our main library for all the other DevOps tools (Kubernetes drivers, Terraform provider…). There are BREAKING CAHNGES in the v2 SDK, so please read the release notes carefully. Remember that the v2 SDK is a beta version and can be subject to significant changes. The current semantic versioning we use is mostly for the v1 SDK. When the v2 SDK becomes stable, the major version number will increase. https://github.com/vatesfr/xenorchestra-go-sdk/releases/tag/v1.11.0

    @Danp I agree with you here, but they also mentioned a "different newly created VM and attempted to install Windows 10 with two hard drives" and they only saw one disk, so was seeing if maybe the issue is related and there is something setup wrong. All disks should be visible to the Windows installer.

    Yeah I'd check BIOS settings like @olivierlambert mentioned here. But also, you mention pass through, this isn't pass through this is vGPU which is different (and only supported by some GPUs in specific), which allows you to have a single GPU that can run multiple VMs. If you want passthrough you'll need to follow the docs here https://docs.xcp-ng.org/compute/ This will let you pass through the entire card, make sure to passthrough all devices that are part of the card (so HD audio and stuff too, everything that is under the same PCI address). I've done this with a few GPUs and it works great.

    I can't say for sure as I haven't tested it, but it may "just work" if you swap them out, a lot of systems do support swapping SFP modules without extra work being done. But again, never tested it at all myself.

    @Danp said in Live Migrate between two stand alone pools fails: It's difficult to know for sure where the problem lies since your XO isn't up to date. Wouldn't the host need to already exist in XO in order for it to be a migration target? Yeah, I had two host connected to this XO instance, just to help get an insight to what is where. I've disconnected the target host, and can see the VM on the desired host.

    That's correct, that's why I asked for a spec, so it's easier to build it while knowing exactly what's requested Okay so we can start simple I will make the issue on GH and we'll see how hard it is, to know when we can make it

    @hitechhillbilly What XCP-ng version are you runing? With XOA Premium up-to-date and the Enterprise support plan, I think it is best to open a ticket and let the support team have a look (especially for a productive environment).

    So I think I figured out my issue. The VMs I was importing were reading off the local storage of the ESX server which is a single SSD. Once I started one that was reading off the the storage device, it went much, much faster. I still have an issue with something else on imports, but I will open a ticket since I have support. Thank you for the help.
