    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

    @andrewperry yes, we replicate TrueNAS to a "standby" TrueNAS using zpool / truenas replication. Our current policy is hourly. We then (plan) to do Incremental replication of all VM's to a standby TrueNAS over weekends giving a 3 possible methods for recovery. Currently we're running into a major drawback with VM's on TrueNAS over NFS (specifically VM's that rely on fast storage such as databases and recordings). We did not anticipate such a huge drop in performance having VHD files over NFS. We're reaching out to XCP to ask them to give us some advice as it could likely be in part due to customization we can make.

    @wildones It's good that the XCP hosts can reach each other, but that's not enough. XOA needs to reach all the hosts too. You may want to use an XO proxy to manage remote locations. Please read the XO proxy guide.

    @BenjiReis I tried to fill in the IP address with brackets, but then the discovery of the NFS shares fails. With regular SRs, it works fine without using brackets.

    In fact it's already possible In your replication job: Edit the schedule, check "Health check" box. Target the same SR than your VM are replicated too And voila!

    @stormi So I looked into the code of the ISOSR and there is a parameter for the version in the device-config. The parameter is vers but it can only be V1 or V3. And if it can't connect with V3, it will also try with V1.

    Hello @Andrew, thanks for your question! First off, I haven't tested Deno or Node with Xen-Orchestra yet. Changing the Node version can sometimes introduce bugs—some of which may be subtle. For that reason, I’d prefer not to venture into this unless it truly proves to be worth the effort. Secondly, in my experience, benchmarks don’t always translate into meaningful results in complex applications. That said, we are keeping an eye on alternative engines, both in terms of performance and the new features they offer. If we determine that the benefits are significant, we’d definitely consider migrating. Additionally, if any users want to experiment with Deno or Bun, they’re welcome to start dedicated threads on the forum to collaborate. We’d be happy to review and merge compatibility PRs as long as they don’t break Node and aren’t overly complex.

    @Danp So I had a problem with ldap, I read older article that mentioned doing this sudo npm install --global xo-server-auth-ldap which coincidently fixed ldap but that is when I noticed sync option were gone. This is just a POC and has noting running, so I will destroy and build new xoa. Thanks for help.

    @tuxpowered said in Rolling Pool Update - host took too long to restart: When the first note reboots (the master), I can see that the system is back up in 5-8 min. If I go in to XO > Settings > Servers and click the Enable/Disable status button to reconnect it pops right up. Again, does not resume migrating the other nodes. That is what I am seeing also, logged here https://xcp-ng.org/forum/topic/9683/rolling-pool-update-incomplete

    The easiest way to guarantee it is to depend on a local resource (local SR or ISO).

    If you proxy (or reverse proxy) any stuff, yes, you need to have a fixed address for the proxy.

    Yes, that's the issue, the max vCPU in Advanced tab. It's probably at 42 while you only have 32 physical CPUs. Therefore, the VM won't boot. See an example screenshot: [image: 1726217639918-8728f260-893b-4601-b8b2-43b39b9d6806-image.png]

    Hi, We offer air gap services to get you pre-bound XOA without the need for any Internet connection Otherwise, the workflow you used works too (configure XOA with a connected env and then export it). See https://xen-orchestra.com/docs/airgap.html for more details. Also, you can use our airgap deploy script in here: https://xen-orchestra.com/blog/xen-orchestra-5-95/#️-air-gap-features
