    @tuxen Doing some research, it doesn't look like the Xeon's I have are affected. But I'm willing to try the next time I need to reboot. Will report back after that.

    The same as @john.c and also XO Lite tends to be less a priority because less critical than the full fledged XO (the priority is to replace entirely XO 5 in the next releases). Why you would need XO Lite outside basic actions? It's mostly meant to bootstrap XO itself and do basic operations (which is already the case, at least with many basic features already). Initially, the goal hasn't moved: replacing XenCenter. We are moving in that direction, but again, I think it's more important to get XO 6 finished first. I'm curious to understand more the use case of XO Lite in your context @unreal-shizzle ?

    Hi, everyone Thank you for your help. I had a flux that was blocked by our firewall. The button worked after that. But it doesn't explain why I lost this configuration and had to reinstall it. Thanks again.

    @jul1an [image: 1782285080688-2026-06-24_101114.jpg] [image: 1782285186489-2026-06-24_101302.jpg] I am using a translator because my English is limited. I have 5 identical servers equipped with Adaptec 6805 controllers. Previously, I bypassed the controller issues by using an alternative kernel, but that triggered network problems—specifically, network bonding is unstable on the alt-kernel.I have tested your evaluation image, but unfortunately, it did not resolve the issue. Later today, after my work shift, I will provide the logs and output from dmesg.I am ready to fully cooperate to fix this and can even arrange remote access via IPMI if needed.

    I'm not aware of such problem it's like the VM was kept in limbo. You did the right thing with your commands.

    Hello, I've tried benchmarking several Windows VMs from another client and am getting expected performance: Read: .\diskspd.exe -c1G -d10 -Su -Sw g:\data.dat Write: .\diskspd.exe -c1G -d10 -Su -Sw -w100 g:\data.dat Windows Server 2022: Read IO thread | bytes | I/Os | MiB/s | I/O per s | file ------------------------------------------------------------------------------ 0 | 1151533056 | 17571 | 109.72 | 1755.53 | g:\data.dat (1GiB) ------------------------------------------------------------------------------ total: 1151533056 | 17571 | 109.72 | 1755.53 Write IO thread | bytes | I/Os | MiB/s | I/O per s | file ------------------------------------------------------------------------------ 0 | 966000640 | 14740 | 92.12 | 1473.98 | g:\data.dat (1GiB) ------------------------------------------------------------------------------ total: 966000640 | 14740 | 92.12 | 1473.98 Windows 11 24H2 (with Eset): Read IO thread | bytes | I/Os | MiB/s | I/O per s | file ------------------------------------------------------------------------------ 0 | 1100283904 | 16789 | 104.81 | 1677.01 | g:\data.dat (1GiB) ------------------------------------------------------------------------------ total: 1100283904 | 16789 | 104.81 | 1677.01 Write IO thread | bytes | I/Os | MiB/s | I/O per s | file ------------------------------------------------------------------------------ 0 | 931594240 | 14215 | 88.82 | 1421.07 | g:\data.dat (1GiB) ------------------------------------------------------------------------------ total: 931594240 | 14215 | 88.82 | 1421.07 Several questions: Are you running benchmarks on a separate virtual disk? If not, could you try again using a share created from a separate virtual disk? Could you run CrystalDiskMark locally on these VMs and see the performance? You mentioned that Eset security takes up 100% CPU during the benchmark. Could you try temporarily uninstalling Eset and testing again?

    Thanks for your feedback. In the meantime, I will plan a "spike" to investigate the status of USB speed on passthrough.

    @andsmith windbg is also a regular win32 app and is included in any recent windows SDK. Here: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ You just need windbg so deselect all the other crap.

    Yes, you can use XO webhooks (IIRC) to trigger something before or after a backup and send the request to a custom agent you made inside the VM. But I'm not sure to get it, can you provide what do you want to achieve, not the technical solution (script VM backup is already a solution, not the problem you are trying to solve)

    We are now live again with all the VMs - which is a relief. The above steps from @stormi were great, the one thing I notced was the /etc/stunnel/certs directory didn't exist. I created that manually and everything else seemed happy. I did have to mess about a bit with the fibre NICs, but I've repeated the previous renaming and that's now running fine. Thanks very much for all the help - I appreciate it.

    There is some diff, but not that much between HyperV, ESXi and Xen. However, it's big enough to require a lot of effort to get nested working correctly, one small mistake and your VM is dead.

    I believe Proxmox Backup Server kernel Linux pbs 6.8.4-2-pve has also the same issue. updating to Linux pbs 6.8.12-1-pve solves.

    @darkbounce Short answer: it seems that Intel hybrid architecture is finding a way to make something that would result of Xen running the VM with the less "featured" CPU, meaning your VM will never use all P core instructions that aren't on E core, meaning... it will work without disabling one or another. Hard to tell how much is lost in terms of perfs vs the best Intel hybrid scheduler (which is on... Windows) but probably not that much on a machine with a reduced number of P cores like this one.

    @yammy I hope you are not talking of installing Docker in the Dom0, because this is really a bad idea.

    @PontusB i don't even know if disabling option 66 solves the issue but as soon as we add option 66 in our DHCP server it boots fine from XenServer (but without HA between the many PVS servers).
