    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    Hello I'm pulling stats for all VMs to understand CPU usage. We're a bit behind the curve in terms of XO versions, but these questions hopefully are still relevant. If using a granularity of days, the interval is set to 86400 (understandably) but the endTimestamp varies. Running this on June 9th @ ~1740 we get timestamps for both Mon Jun 8 01:00:00 AM BST 2026 and Tues Jun 9 01:00:00 AM BST 2026. Does this average across the day? Why is the timestamp 0100? Why would there be different timestamps between VMs (all are running) and does that mean that the figures are misaligned in the results? These are retrieved via curl and a bash script, a bit hacky, but for clarity the request is: ++ curl -X GET -s -H accept:application/json -b authenticationToken=[[REDACTED]] -o [[REDACTED]] 'https://[[REDACTED]]/rest/v0/vms/[[REDACTED]]/stats?granularity=days' Really keen to know if we can control the start and endtime, as well as provide a manual interval, as well as the aggregation strategy (min, max, average). Are any of these possible? Lastly, is cpuUsage the percentage as per the dashboard, but averaged over all CPUs? Thanks so much in advance. James

    The Kubernetes CSI driver for Xen Orchestra just hit v0.4.0, and we want it on more real clusters before it reaches a stable release candidate. If you run Kubernetes on XCP-ng VMs, this is a good time to give it a proper workout. What's new in v0.4.0: Local-storage support Automatic pool-discovery fallback Kubernetes metadata now lives in Xen Orchestra VDI tags instead of the deprecated other_config. That change also drops the old requirement for Xen Orchestra 6.4 or newer, so the driver runs on more deployments now. ️ Read this before you upgrade. v0.4.0 is a breaking change. The Kubernetes metadata moved from other_config to VDI tags, so you must migrate before upgrading from v0.3.0. Do not upgrade in place: follow the v0.3.0 to v0.4.0 migration guide in the release notes, then move to v0.4.0. What helps us most is hearing how it behaves on your own setup: what works, what breaks, which storage backend you use, and which flavour of Kubernetes you run (k3s, full k8s, or something else). Edge cases on real clusters are the ones we don't see in our own testing. Where to report: start right here in this thread. It keeps everything visible to the community and lets others on the same setup jump in. If something turns out to be a reproducible bug, we'll move it to a GitHub issue on the repo so the team can track it to a fix. Release notes and migration guide: https://github.com/vatesfr/xenorchestra-csi-driver/releases/tag/v0.4.0

    @DKirk That all makes sense, thanks for clarifying. Looks like there are further comments below that seem to pinpoint where the issue may lay. The key point you make is only "after the last updates" is when this started happening!

    Olivier, I can say it's worse without the VGA being selected to 16Mb. That option is pretty much a must for any desktop virtualization. The novelty for me is people get far above 1080...

    @olivierlambert Thank you for your response. I have followed most of the documentation on setting up HA, and made sure that I have 3 hosts. All are Dell 7090 64GB RAM with 2 dedicated HA NICS. XCP-ng 8.3 is patched, XO is up to date, Xen tools 9.4.0 on all Windows VMs, and using the Xen tools ISO that can be mounted. eth0 1Gbs management network eth1 10Gbs iSCSI network DAC eth2 10Gbs VLAN Trunk, including backup network eth3 1Gbs HA eth4 1Gbs HA Overall, XCP-ng and XO are doing an excellent job. I feel like I am on an Easter egg hunt when pouring through documentation, but that is mostly my problem, because I see that you have put a lot of effort into organizing and updating it. My "use case" is replacing the VMware ESXi/vSphere 2-node cluster with XCP-ng and XO at the small high school (non-profit) where I volunteer as the IT guy. I feel that I am at the point where I trust XCP-ng and XO enough to make the switch during the summer break. Sorry to run on. The yellow triangles behind the non-master hostnames are just a small nuisance. I do notice that the hosts are hard to shutdown. Sending a shutdown command from either XO or from the host console causes a host to reboot, but not shutdown, even after having previously entered maintenance mode. I feel that this is not a big issue, just another small nuisance. The XO cluster is maintaining the integrity of the guest VMs. I will be reading all of the documentation I can, and upgrading to 8.4 when it is available. Thank you for supporting your awesome hypervisor.

    The plugin was initially created to check RAID created during install, not custom RAIDs created manually. But that could be an improvement to the plugin @stormi I leave you the honor to add this somewhere

    Cannot get to XO Lite portal

    @Virtual said in Cannot get to XO Lite portal: @olivierlambert So my host IP is 192.168.1.40 and the Xen orchestra IP is 192.168.1.45 To clarify, I was referring to XO 6 Lite. Going to https://192.168.1.40 brings up the page with XoA quick deploy, cli documentation, etc. It doesn’t navigate to XO 6 lite Going to https://192.168.1.45/v6 still gives me the error mentioned in the original post Indeed, as said, there's no such thing as "XO Lite 6". XO Lite is simply "XO Lite" (we'll have a v1 at some point, v6 is like far far in the future ) So yes, https://192.168.1.40 should display XO Lite if you use XCP-ng 8.3 (you can install it manually for 8.2 but it's not bundled by default) And https://192.168.1.45/v6 should display XO 6, only if you built it correctly to get XO 6 components built.

    Edit to my previous post: the script is checking for working DNS, so i cannot pre-setup network. If you want the fixed applicance with the drivers installed, ping me ! To setup the network, you just need to login (root/changeme, yeah the password is... bleh), and launch the script /usr/local/brs/puppet/scripts/install.sh -lui

    @RawbDeeni Thank you! I had the same problem using 8.2 lts. I ended up formatting and using 8.3, and I didn't have any issues after that. I'm glad I found a better alternative to use this hypervision from a vmware end user for over 10 years until Broadcom killed it.

    @tuckertt Hello ! We are making some investigations on authentication, users, ACLs etc... topics for the Xen Orchestra 6 version to come. Could you please formalize your need so I can add it to my user suggestions list? Try to make specs as most generic (for all users) as possible, and don't hesitate to add some concrete examples. Have a good day!

    @AtaxyaNetwork said in XO update fails: @edisoninfo Hi, What's xo-install.sh ? It's a third party script ? Very likely indeed Those scripts really needs to make sure to provide the URL of the repo to report issues in a very visible way.

    @Danp No sir, I have not. I have, however, exported the same VM in the OVA format. Ended up being about 47 GiB, however, I was able to import it into XOA without any issues, and the import took just under 10 minutes to complete.
