    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

    @julien-f Maybe we do not differentiate "attaching" a disk and "connecting" a disk. I just created a new disk then went to a VM to attach it, then did the same on another VM without problem on XO UI. BUT it seems that I cannot "connect" it on both VMs, which is not a problem, I only need to know what's possible, and what's not to be able to handle it. Regards

    Having XO from source or XOA act as a certification authority for the XCP-ng hosts is for sure a good approach. Would be great if that could include the VMs running on the XCP-ng hosts, which is my main goal (apart from being able to HTTPS into XO from source of course).

    @olivierlambert this is an old command. Replying because this shows up in a Google search result. The current command is: xe vm-destroy uuid="uuid of VM" (without the quotes)

    @JacobyBarr Unless I missed it, you still can't use secure boot with those ones, so that can pose an issue in some environments.

    @olivierlambert said in Feature Request: XCP-ng. The idea is to make it open via a XAPI call when needed (or automatically when XAPI is down). @guiltykeyboard A bit similar to how VMware ESXi handles SSH server, it has SSH stopped and/or disabled until requested in its web interface. Unlike possibly VMware ESXi its going to automatically enable and start the SSH server if XAPI is down!

    @olivierlambert I would agree... one of those odd glitches that occurred during the build process that corrected itself on a second run. Thanks for everyone's help... please go ahead and close this out!
