    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 said in Backup Error: "302 Found": @DustinB You could try the same backup job using XOA. If that works correctly, then that would eliminate some of the environmental causes. Got it sorted out, and addressed a speed issue I was experiencing. The advanced options of the pool, I had set ETH1 as the backup network, which for some reason keeps falling back to 10FDx and is generally just bad. Undid that change as well as moved my XO over to a different vNIC which appears to have addressed the issues.

    Alright I updated XO again and the problem is gone. I would just like to comment that unlike described by another user that was only happening on single-node installs, this was happening to me in 2 out 4 nodes in a cluster. Two hosts would show normal, and another two showed glitched. Anyway, SOLVED!

    I'm talking about VM snapshots (and by transitivity, VDI snapshots). Retention is the number of backup you save on the backup repository, and it's totally unrelated to the number of snapshots when doing full or incremental backups.

    The code is entirely open source. It's just that the deploy is exposed in the XOA UI

    Of real RAM usage? Eg with htop, take care of the cache too, because even if the cache is used doesn't mean it's really important. Maybe 8GiB is enough for example.

    Nothing like that could happen. If your orphaned VDI is in use, it will error out with "VDI in use".

    @olivierlambert I can do it pretty easily, but there may be a good reason for XAPI to throw this error instead.

    @shinuza The version inside the Debian image and the version on GitHub may be different. It is likely that there will be more recent versions on GitHub. Just don't select a version and the latest version from the Debian repository will be installed. const k8sInstall = k8sVersion !== undefined ? `apt-get install -y kubelet=${k8sVersion} kubeadm=${k8sVersion} kubectl=${k8sVersion}` : "apt-get install -y kubelet kubeadm kubectl";
