    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

    Depends on what you expect from "manage", but once a template is deployed (or recipe applied), it's all regular VMs.

    I think using a script for an initial test is OK, but if you want to really use it, it's better to follow our documentation and following the per-requisites by the book.

    In essence, you can write any script you like in your VM that would be executed, test whatever you want in the database, and if it's OK, write a special key in the XenStore. XO will detect it and consider the backup health check done and working

    What kind of backups are these? Incremental (delta), full, etc..? I think that'll help determining the issue, I had something similar once specifically with an incremental and was able to fix it. May not be related though since that was a while ago and on stable release channel for XOA.

    Hmmmmm I need to look back through some of my old posts and notes but I had a similar issue with a VM with large number of disks. The disks themselves being big wasn't the issue, it was just having a huge number of them that eventually cased a problem. Ended up migrating by moving a single VHD and rebuilding things (the specific system didn't really "need" all the VHDs so it was an easy fix for me, wouldn't be the case here haha). If you are trying to reduce the number of hosts though, why would migrating the VCSA help? If you're powering off a host then wouldn't you not need the VCSA to be running anyway? Or do you have more than 1 ESXi instance? Might be easiest to just migrate it to another ESXi host if that's the goal, since you won't need the VCSA once you fully move to XCP-ng (assuming you are doing so).

    You can create a valid VHD file with the command uuidgen

    If you want to put VHD file in an existing NFS SR, you need to indeed have an UUID type. Note that the SR file structure should NOT have any subfolder into it. To generate an UUID, you can use uuidgen command.

    Don't forget to always stay up to date to the latest commit as possible, because there's no support on older code for the version on Github
