    @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.

    @AtaxyaNetwork Thanks for your guidance. I can create a lightweight Debian VM with an NFS share for the ISOs. But even so it is strange that the drive is not known by the XO. Maybe other people can comment on this later.

    @furyflash777 I'm assuming you're on Ubuntu? Indeed as Olivier said this is tested on Debian and doesn't cause issues, but it seems on the newer Ubuntu versions with cloud-init, the new Netplan based network manager and how it interacts with cloud-init breaks/gets wiped if no cloud-init drive is found. Yet another cloud-init bug to track down

    Hi, "It depends" is the answer here Depends on: the number of concurrent users on your XO instance the size/frequency/number of backup jobs you have the number of hosts and VMs managed by XO Frankly, for a small setup (less than 4/5 hosts) with one users and few backup jobs, the default 2vCPU/2GiB RAM is enough. Especially since we improved various process to happen in a dedicated worker

    @lawrencesystems We added the healthcheck for full backup (here : https://github.com/vatesfr/xen-orchestra/pull/6401 ) Also we removed our js smb implementation ( https://github.com/vatesfr/xen-orchestra/commit/b50e95802c6a876d4e6ffd0c62c209a187b1bfb2 ) to try to circumvent the strange samba comportment fbeauchamp opened this pull request in vatesfr/xen-orchestra closed fix(backups): add healthcheck to full backup #6401 0 julien-f committed to vatesfr/xen-orchestra feat(fs): remove JS based SMB handler It's not well tested nor maintained.

    There's no black magic As @ronivay said, you need to tell the filesystem inside your VM that the disk grew. On Cloudinit-enabled VM, there's an auto-grow parameter that is checking at each boot if the disk was extended, and will automatically do it for you. But again, that's inside the VM. Keep in mind: it's not the job of the virtualization system to deal with what's inside the VM

    @olivierlambert Thanks for that information, will use it next time I run into the issue. Before I read your above reply, I was poking around and noticed that the only SR I had added was disconnected, somehow. So I researched into it and discovered that this was my own doing. Without going into too much detail, I had converted my Active Directory environment from a Zentyal server to a Windows Server and I was hosting the SMB share on the old domain controller. So I had made a DNS error which was causing the SR to not be reachable from the XCP-ng host. So I deleted the SR and recreated it and viola I was able to create the VM. Honestly, I'm not sure how the two are connected since I'm not storing any disks on this SR; I only use it for ISOs which I mount into the newly created VM to install an OS and then I eject it. Long story short, my problem is solved but I'm still confused as to how it happened.

    @mjtbrady compression is used ( brotli, fastest mode by default) There is a problem on the size reported especially with encryption. I will add a task to the backlog to fix it (there is padding with encryption, that complexify the maths)

    Indeed, if your other hosts are somehow dead/unresponsive from XAPI perspective, ejecting them from the pool is an option to get your master booting those VMs

    @pdonias I am puzzled. What do you see? To be clear there are two problems. The selected directory truncates the directory name at around 46 characters ("/var/lib/docker/containers" in my original screen shot isn't truncated because it isn't that long). "Long" file/directory names in the "Select a file" drop down do not display correctly. Once a file has been selected, the "Selected files/folders" does show it in a scrollable "widget" that can then be used to see the full file name. My screen shots are from Chrome on Fedora. I normally use Fedora/Firefox which has the same issues. I set up the following as a test. Filename lengths are 10-80 characters long. root@debian42:~/testdir# pwd /root/testdir root@debian42:~/testdir# ls -l total 0 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 1234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:50 12345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 1234567890123456789012345678901234567890123456789012345678901234567890 -rw-r--r-- 1 root root 0 Oct 7 09:51 12345678901234567890123456789012345678901234567890123456789012345678901234567890 Filename lengths 10-50 display.

    @olivierlambert i did update xoa again but no dice, i was wanting to export a couple VM's and do a head to head iscsi I/O test between vmware and xcp on identical hardware but not having much luck trying to get my VM's out of xcp. Guess I'll have to wait for this to work possibly.
