Logs from xen04 look like they are the same too. Which makes sense. 20:01:53.805: The Linstor DeviceManager on xen04 triggered an asynchronous alignment for a newly created volume (pvc-fac0a18b-2c23-4fe8-b005-b4f492cec92f), padding it from 26220040 KiB to 26222592 KiB. 20:01:54.034: Simultaneously, an orchestrator (like Velero) began tearing the volume down, shifting the DRBD state to conn( Connected -> TearDown ) and pdsk( Diskless -> DUnknown ). 20:01:58.484: The DRBD worker thread evaluated the shrinking bitmap while the alignment was trying to alter it. This caused the general protection fault: 0000 [#1] SMP NOPTI at instruction RIP: e030:drbd_bm_count_bits+0x223/0x300 [drbd], crashing the kernel.

@TeddyAstie From what I've tried...It won't work at all in Linux. It kind of works in Windows, and while I do see some load on the GPU when running something, there's as much if not more load on the CPU. It's not what I expected at least. I've never really gamed on PC, and definitely never Linux. My only uses for GPU's have been in media composition which was always on dedicated systems and Nvidia GPUs. More recently I've been doing some AI tasks, again with passed-through NVidia GPUs. Side tangent... I ran into another workload last night where the app wanted OpenGL...But OpenGL doesn't work with the "normal" VGA adapter in XCP-ng, and I don't have a GPU on that particular pool to try a pass-through. That lead me to VirGL, but it doesn't look like that's gone anywhere.

@pierrebrunet Hi! I'll send you xo logs of the errors. In the meantime, I've deleted "Long-term retention of backups" settings and I no longer get duplicated VMs on the DR pool. [image: 1784562046612-cb037ec5-7ad7-4c3f-8a76-1b5be06574f7-image.jpeg] So it seems that this setting is also being used for replication and I cannot use it. Don't have the space for it on my storage, with thick snapshots on lvmoiscsi.

@poddingue Thank you for all the details and advise. I will reach out to them to see if it is anywhere on the project horizon. Thanks much, and have a great day!

@Bastien-Nollet Perfect, thanks Bastien! Thanks for looking into this, I really appreciate how responsive everyone at Vates is on this forum.

Thanks a lot @msupport ! @all-ki could you add this to our IPMI doc to be published ?

Perfect, thanks for your feedback!

@pierrebrunet said: Hi, just to be sure, are you saying it is working ok apart one task 8 days ago? Yes, after I adjusted the time it's working

@pierrebrunet Hello! I've checked B2 logs and found some errors like you had foreseen. I had a look and this kind of 500 INTERNAL ERROR several times on other jobs that seem ok. How many retries does XO attempt to send the part when this happens? I'll do another run that includes only a few large VMs. BTW, is there a way to interrupt the job withou restarting XO ?

@simonp , thank you very much and all of your team ! ! ! Keep up the outstanding work. Regards, Marc

Hi @acebmxer, thanks for reporting, we identified this bug internally already, we're going to fix it once root cause is found.

Hi Everyone, If I may advertise what I did you have a dedicated thread about my project, this is an easy to setup XCP-ng and XO from the source solution. Sorry sharing the link to the topic as is couldn't find better way to do that : XCP-ng HL — an ISO for home labs, deploy any XOA image from XO Lite directly Essentially you deploy XCP-ng ISO and then in XO Lite deploy XOA section you can deploy your prebuilt or XOA VM directly. Hope that helps Home labers to get in to XCP-ng easily. Same here this is still work in progress, also I'm personally already using this version in my lab. Any feedback is welcome ! With regards.

@acebmxer I can confirm that, we'll fix it, thanks

Just FYI, we had some issues with some Debian VMs for instance, with old kernel where the VM would suddenly take 100% CPU and would we completely frozen and unresponsive. It was in fact Debian enabling the suspend, the guest would suspend and trigger a bug in xen PV driver in the guest kernel which would never be able to wake up anymore. Newer kernel don't have this issue and are able to wake up. I'm quoting Debian here but it might very well happen on other distro

Hi @dvdwx, RBAC is available only at the REST API level, not through the XO6 UI. UI compatibility with RBAC is currently under development. For the topology, this is something that has been here for a long time, so I may be wrong since I don't have the full history. However, if I look at the code, creating the topology selector requires knowing how many CPUs are available in the pool. Since a self-service user doesn't have visibility into the pool, they can't access this kind of information.
