    @dinhngtu Yeah, I suspected that as well. So I inspected the SR and it showed connected to both hosts (at least in the XO UI - I didn't drop to the CLI to really confirm). By altering my workflow a bit and slowing down, I seem to have found the right "sweet spot" of delay and the issue hasn't resurfaced. Here's what I'm doing now, when I need to revert the snapshots of all three VMs: In the XO VM list, I select the three VMs and power them off at the same time. I then start with VM1 and eject the ISO, VM2 and eject the ISO, then VM3 and eject the ISO. By the time I circle back to VM1 for the next step, about 10-15 secs have elapsed. I then start with VM1 and revert the snapshot, and repeat the same on VM2 and VM3. By the time I circle back to VM1 for the next step, another 10-15 secs have elapsed. I re-attach the ISO to all three VMs in sequence. Another 10-15 secs elapse. I then start with VM1 and power all three VMs sequentially. The entire workflow takes about 30-45 secs, and I'm finding that by doing this, the issue hasn't resurfaced.

    Howdy all! I have a backup configuration that's been working fine for years. It's for some non-critical VMs, but recently, one of the VMs mysteriously started failing. Since it's not critical, I just sad 'screw it', and deleted the backup and recreated the configuration. This completely new backup is still failing, and only on that one problem VM. Error: stream has ended with not enough data (actual: 397, expected: 2097152) Error: ENOENT: no such file or directory, stat '/opt/xo/mounts/9f2e49f9-4e87-444a-aa68-4cbf73f28e6d/xo-vm-backups/afe4bee2-745d-da4a-0016-c74751856556/vdis/7fc5396a-5383-4dab-91fe-6758eb8b7474/530abab7-9ea9-43d4-be6e-acb3fbf67065/20260323T124158Z.alias.vhd' I re-ran it, and got some more info, but that could just be that the initial backup failed in this new backup configuration...

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    That's a way to do it. Use smart backup on tags. Eg a tag called "delta only" and a tag "delta+CR", so you'll be sure to assign the right tag to your VM

    No. The parent folder. XO will search for the folder xo-vm-backups directly edit: if your share was previously <NFS_IP>:/myshare, then you should use this very same one, and NOT <NFS_IP>:/myshare/xo-vm-backups

    There's 2 reasons: XAPI doesn't tell us if the transfer is complete or just cut. We just stop to receive chunks, and after a bit, we decide that's it, there's no more data to send (that's the normal behavior even when it works!) XVAs are hard to validate, depending on various factors. We do a VHD validation (so for delta backup) but XVAs are another thing

    On the remote side, right? It won't be "dedup" if it's your question (for now at least). We are thinking on a smart way to dedup it efficiently It's not trivial because we don't have a lot of control on the host itself, but we might find solutions.

    @nraynaud well i just used the datastore browser to download the vmdk. i did the same thing with some other (smaller) VMs without any problems. All of this from the same ESXi host. Thanks for looking into it though, i will try the export VM way next but have to find the right time for a shutdown ...

    That's correct @mauzilla We use a VHD chain on destination so it's equivalent to get "snapshots" of a VM So it's delta everywhere with the same full parent for the same original VM.

    The delta isn't computed over the network, but directly on the host itself

    @slynch OK, that's very good news then! Debian was still having issues where any configuration applied via cloud-init would just be added to the existing default DHCP config, unless you took care to build the VM without the default interfaces config beforehand.

    @olivierlambert said in PCI Passthru Error not working on 8.2 but was 8.1: Hi! IOMMU should be enable in the BIOS. Double check that Also please share your grub config to see if it's correctly written. After playing with it more, the issue appears to be passing multiple devices of the same type. In this case RADEON WX7100. If I take it down to one card it works as expected. If I add more than 1, pick any quantity, then I run into the issue. The issue goes away once I reboot the host, and then I can assign a card, but the second the VM reboots the error comes back

    This can happen from time to time on master (despite we do every "broken" code in dedicated branches), sometimes you can have a surprise. That's why it's important, before anything, to get the latest commit and rebuild, to see if the issue persist. If it's the case, then reporting the problem will be helpful
