    @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

    @adzmedia Hi adzmedia, I can give my nails cut for the fact that this is due to the overall slowness between the xcp-ng and XOA. I've been having similar issue and was pulling my hair, in a usecase where my xcpng was on the other side of the VPN wire, and the virtual console of the VM, could not be drawn on time to allow me hitting any key to run the content within the mounted iso. (in my scenario I I've been using xcp-ng centre) this issue become the relict of the past, when I did the same thing within my network (still over the vpn but utilizing a RDP of the machine within the LAN network). maybe apache quacamole will do the trick for you, to expose some way of reching it out. think about it. ps. I've been having this with BIOS / UEFI, at first place I thouht this is an uefi, but it was not.

    I opened that ticket myself. But it's an old bug that should have been solved or not reproduced since. You should at least upgrade to a supported version to see if it's still happening.

    Well, if you pay for an LTS version with active support on it, indeed, update to a more recent version shouldn't be the solution to a bug. But there's no such thing as LTS for Xen Orchestra, since there's a monthly release cycle. And I'm not aware either that you are paying for it

    @bberndt the sdn controller communicate with the hosts on port 6640, opening it on the host should be enough. I don't know what's happening. !this TLS error should have been solved by the override-certs option set to on.

    @brodiecyber Looks like it was some fluke with the way i scheduled the backup job as after i reorganized the times for the backup jobs im not encountering the error anymore. so entirely my fault was experimenting with incremental backups Thanks

    @gojjily Hi Gojjily, Not sure i fully understand your question so let me clarify some points and perhaps you can ask some questions after that. XO allow you to make backups to what we call a remote, this remote is a network share (or local but not recommended) inside the XCP network where you can store your backups. You can also backup XCP metadata this allow you in case of a major crash of one of your host to restore the host configuration. Once your backups are setup you can restore them directly from your XO. If you want to protect further your data you could copy your backup to another place but it's not directly include in XO even if you could set two remotes for the same backup job and have you backups directly replicated hope this clarify a bit.

    Is there any option to set for timeout value? I say this because, monitoring the process, everything seems to be going well until the moment when it starts to check the free space. XCP-NG is 8.2 up to date, the disk on which the VM is it is formated as local ext. The connection to the backup server is on NFS on the LAN at a speed of 1Gb. On the iotop it seems that the space check goes with speed 650Gbits +.

    @darkbeldin For the record, both vm's were running on the same esxi host when exported. This may or may not be a factor (I suspect it is).

    @olivierlambert I've dug into the issue a bit more, and it just gets stranger. Downloading to my Macbook on the same network gets ~4MB/s. This means there is something strange going on with the control domain around remote downloads. When I test the disk speed (which is an Samsung NVMe), the speed is 1.7GB/s: [14:31 xcp-host ~]# dd if=/dev/zero of=testfile oflag=direct bs=1M count=5000 status=progress 4998561792 bytes (5.0 GB) copied, 3.000607 s, 1.7 GB/s 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB) copied, 3.15049 s, 1.7 GB/s When I test the network speed with Ookla's speedtest-cli it confirms a 1G connection, and a 1G transit to Europe (checked this twice because 1G Atlantic transits are rare): [14:44 xcp-host ~]# speedtest -s 2023 Speedtest by Ookla Server: LaFibre.info - Lyon (id = 2023) ISP: Bell Canada Latency: 108.05 ms (0.49 ms jitter) Download: 960.47 Mbps (data used: 1.5 GB ) Upload: 172.11 Mbps (data used: 293.4 MB ) Packet Loss: 0.0% Result URL: https://www.speedtest.net/result/c/b8f1da9f-5c57-4ad8-ad3b-729e1625affe On my Macbook (on 802.11ac) I can download an Ubuntu image at ~14MB/s ➜ wget http://ubuntu.mirrors.ovh.net/ubuntu-releases/21.10/ubuntu-21.10-desktop-amd64.iso --2021-11-16 14:49:41-- http://ubuntu.mirrors.ovh.net/ubuntu-releases/21.10/ubuntu-21.10-desktop-amd64.iso Resolving ubuntu.mirrors.ovh.net (ubuntu.mirrors.ovh.net)... 213.32.5.7 Connecting to ubuntu.mirrors.ovh.net (ubuntu.mirrors.ovh.net)|213.32.5.7|:80... connected.

    Well, it's a bit hard to tell you directly what to do vs XOA, because on XOA you are already on a validated OS (Debian) with some packages installed. On which OS did you install Xen Orchestra in the first place?

    Sorry for the huge delay, I just stumbled on this thread It's indeed the case now, XO automatically check the integrity and clean any unused files in VM directory on a remote when that VM is backed up.

    @olivierlambert said in Commands in Xen Orchestra Jobs no longer working: The best solution is to rely on XOA, you know I agree with @olivierlambert! Personally, I'm using XO from sources in my home lab environment -- nothing is "production" and I'm mostly having fun trying to give back to the open source community.

    @Danp - thank you. Yes, I did, but that was not helping in this case. Found the solution: Both machines are on a hostserver, which has NOT all networks. So the real reason must be a network problem, therefore a quite missleading error message After moving both VMs to the master of this pool (which is connected to the same network where the xoa resides), everything went fine. Same storage, same vhds.
