    @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.

    @itservices Hi, xen-bugtools is in xcp-ng hosts. You can directly get the logs from the hosts if you don't have the command.

    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.

    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.

    @MrNaz I recommend reading the XO blog; updates are published monthly. NBD was introduced in the 5.76 release and the ability to enable in the Xen Orchestra UI was introduced in 5.79 https://xen-orchestra.com/blog/xen-orchestra-5-76/ https://xen-orchestra.com/blog/xen-orchestra-5-79/ Also enhancements were released in 5.81 https://xen-orchestra.com/blog/xen-orchestra-5-81/

    Old thread i know but i will say that there is an issue with using VLAN.id 1 I am permitting all vlans end to end on my infrastructure and the only vlan that doesnt work is 1. If i move the VM to another vlan then everything works. I suppose the solution is to not use vlan.id 1 but thats terrible. all vlans are permissiable.

    @elvintmp75 @elvintmp75 said in XO Proxy Comminuty edition Config Error: I'm probably missing something obvious..any ideas? Yes ! You forgot to read the instructions properly. It is clearly stated: "This script is not supported or endorsed by Xen Orchestra. Any issue you may have, please report it first to this repository." This means that this script/ install method is NOT made or supported by Vates (The guys behind Xen Orchestra / XCP-ng ) There may be errors in scripts and installs which you should report to the creator and not to this forum !

    @olivierlambert Thank you and your team again for your commitment to this fantastic FOSS tool and for allowing me to build it myself! I very much appreciate the personal touch of my issues being triaged by the CEO and Co-Founder. It's refreshing to see an executive officer stay in touch with their customer base.

    Hi, Indeed, only root user in the guest can read it Any user that can see the XAPI object will be able to read it So I would say it's "reasonably safe", but it all depends on your global usage context and level of confidentiality you need.
