    @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

    You can try to "attach" broken VIF to some network and then delete it. Try to use this command xe vif-move If that doesn't work, you can shut down the XO VM, detach the disk, deploy a new VM without a disk, attach the XO disk to the new VM.

    @splastunov said in File restore not finding any option: If nothing will help and you can't import xva with import VM, I have solution. Deploy new VM with disk x4 times greater than backup file. OS Ubuntu 16.04 or later. Copy backup. Take attention. You need always copy backup. Do not move it. Install xva-img https://github.com/eriklax/xva-img add-apt-repository ppa:ubuntu-toolchain-r/test && apt-get update && apt-get install -y gcc-7 cd to xva-img dir and run next command cmake ./ make install Extract xva file tar -xf my-virtual-machine.xva -C my-virtual-machine chmod -R 755 my-virtual-machine In folder my-virtual-machine you will find some directory like Ref :1, but maybe with another number. Remember this number. Create raw disk from extracted. Replace 1 with number from previous step. xva-img -p disk-export my-virtual-machine/Ref\:1/ disk.raw Install qemu-utils apt install qemu-utils Convert raw to vhd qemu-img convert -f raw -O vpc disk.raw [vhd-name-you-like].vhd Copy vhd to some SR. I'm using local SRs, so in my case path is /var/run/sr-mount/[sr-uuid] Go to the host, cd to SR folder, get VHD uuid, rename VHD cd /var/run/sr-mount/[sr-uuid] vhd-util read -p -n [vhd-name-you-like_from-step-8].vhd mv [vhd-name-you-like_from-step-8].vhd [uuid].vhd Rescan SR Attach VHD to existing VM or deploy new one Get you files wow. I am getting on with this in parallel. Thank you again! Results for both suggestions and requests are coming!

    I am no iSCSI expert, I don't know if this settings exists, but before tinkering I would do some benchmarks.

    @vincentp I'd personally go with a 10GbE switch just to be sure there are no bottlenecks from that, I don't really think you'll hit full 10GbE for a replication job but it's better to alleviate that IMO.

    @abelaguilar Sounds good, yeah I think that is the easiest method to go about it, rather than direct attached networking.

    @RaHu In theory you would want to change the MTU of parent interface in OPNSense to 9000. In my case testing is not possible since I run all vlans off a since interface (2x10gbe NIC) and do not want to change the MTU of systems outside my virtual environment. Anyways, with the change mentioned above you achieve 10gbe speeds between VMs.

    @SNSNSN Indeed, these would typically at least be isolated via vlans at least (one vlan for iscsi traffic, one for iscsi). There's no point in having them in two different subnets if they're in the same network and vlan, the traffic isn't isolated at all. You might as well have them in the same subnet if you're doing that, in which case you only need 1 IP on the XCP-ng management NIC.

    @KimmoJ I wonder how much you pays to Vmware? + Probably you have to pay also to your backup software...
