    @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

    @olivierlambert Thank you for your response. I have followed most of the documentation on setting up HA, and made sure that I have 3 hosts. All are Dell 7090 64GB RAM with 2 dedicated HA NICS. XCP-ng 8.3 is patched, XO is up to date, Xen tools 9.4.0 on all Windows VMs, and using the Xen tools ISO that can be mounted. eth0 1Gbs management network eth1 10Gbs iSCSI network DAC eth2 10Gbs VLAN Trunk, including backup network eth3 1Gbs HA eth4 1Gbs HA Overall, XCP-ng and XO are doing an excellent job. I feel like I am on an Easter egg hunt when pouring through documentation, but that is mostly my problem, because I see that you have put a lot of effort into organizing and updating it. My "use case" is replacing the VMware ESXi/vSphere 2-node cluster with XCP-ng and XO at the small high school (non-profit) where I volunteer as the IT guy. I feel that I am at the point where I trust XCP-ng and XO enough to make the switch during the summer break. Sorry to run on. The yellow triangles behind the non-master hostnames are just a small nuisance. I do notice that the hosts are hard to shutdown. Sending a shutdown command from either XO or from the host console causes a host to reboot, but not shutdown, even after having previously entered maintenance mode. I feel that this is not a big issue, just another small nuisance. The XO cluster is maintaining the integrity of the guest VMs. I will be reading all of the documentation I can, and upgrading to 8.4 when it is available. Thank you for supporting your awesome hypervisor.

    @Virtual said in Cannot get to XO Lite portal: @olivierlambert So my host IP is 192.168.1.40 and the Xen orchestra IP is 192.168.1.45 To clarify, I was referring to XO 6 Lite. Going to https://192.168.1.40 brings up the page with XoA quick deploy, cli documentation, etc. It doesn’t navigate to XO 6 lite Going to https://192.168.1.45/v6 still gives me the error mentioned in the original post Indeed, as said, there's no such thing as "XO Lite 6". XO Lite is simply "XO Lite" (we'll have a v1 at some point, v6 is like far far in the future ) So yes, https://192.168.1.40 should display XO Lite if you use XCP-ng 8.3 (you can install it manually for 8.2 but it's not bundled by default) And https://192.168.1.45/v6 should display XO 6, only if you built it correctly to get XO 6 components built.

    Sorry for the delay, I'm a bit swamped. That does not ring a bell to me right now. What is you setup like? How many pools, how many host per pool, is there bond on some of them? Then, more to debug what was actually created as you stated there network does exist but there is no traffic: On your hosts: xe network-list to get the uuid of one of these private networks you created xe network-param-list uuid=<netwok-uuid> should tell you in which bridge they are ovs-vsctl show shows all bridges and their ports, in there you should be seeing the bridge you found in previous step. This bridge should have: a port with type vxlan and options in which you have a remote_ip to the network center the VIFs for the VMs On your VM: is that network assigned to the VMs? do the VM have new devices created in ip link or similar when you attached the network? is there any error in VMs dmesg on device creation? We'll see from there if we can get an idea of what is happening.

To setup the network, you just need to login (root/changeme, yeah the password is... bleh), and launch the script /usr/local/brs/puppet/scripts/install.sh -lui

    @RawbDeeni Thank you! I had the same problem using 8.2 lts. I ended up formatting and using 8.3, and I didn't have any issues after that. I'm glad I found a better alternative to use this hypervision from a vmware end user for over 10 years until Broadcom killed it.

    @tuckertt Hello ! We are making some investigations on authentication, users, ACLs etc... topics for the Xen Orchestra 6 version to come. Could you please formalize your need so I can add it to my user suggestions list? Try to make specs as most generic (for all users) as possible, and don't hesitate to add some concrete examples. Have a good day!

    @AtaxyaNetwork said in XO update fails: @edisoninfo Hi, What's xo-install.sh ? It's a third party script ? Very likely indeed Those scripts really needs to make sure to provide the URL of the repo to report issues in a very visible way.

You can try it out if you're not running a production system. Gosh, we are now officially faster than Citrix to detect and fix bugs even in the Windows PV driver
