    perhaps "in the context of a proceeding RPU, do not start halted VMs" ? or "boot only halted VMs that have HA enabled" ? but I can imagine corner cases where this is not wanted. some chicken & egg problem.

    Good moaning... The solution was pretty simple: a toolstack restart on the master (xcp83) did get all back on track and it now allows me to move the systems with a simple shutdown/start.

    @yannsionneau said: Can you retry with an up-to-date xcp-ng 8.3 please? FYI on recent XCP-ng 8.3 versions the pci-passthrough will enable the ROM expansion bar. The guest VM will have access to it, so no need to pass it via qemu anymore. See my comment on GitHub: https://github.com/xcp-ng/xcp/issues/786#issuecomment-4281846490 Regards, Yann I tried, yes. I confirmed as well on github that the patch does what it suppose to do - it exposes ROM BAR, but that alone is not sufficient to get our cards working. More in my other topic.. I believe it will still fix a lot of issues, and it could potentially fix amd gpu passthrough for some card, but not Phoenix, Raphael and this generation of Ryzen iGPUs (not sure specifically about Barcelo).. But it is a good progress anyway as I wouldn't be able to fix this ever on my own, so I am really glad it is done. Now I will probably get back to the topic and try to patch whatever else is needit and give it to people in a form of rpm package for the time being.. we will see, it is all about time

    I know this is old but I had a similar issue. In the end I told dracut NOT to reassemble my raid array which allowed the system to boot perfectly after. I have no idea why it tries to assemble the same array two but on the second seems to be important

    @dinhngtu I think it just have been a bad migration or the Win 11 Template did other things to the windows 10 os. Since new test vm did not show the time issues, and a fresh migration of the vim with correct template selected did not have the issues either. I dont know but maybe there is a way to put detect the correct VM template or make note. I didnt think using the win 11 template would have caused issues since using the "wrong" template on vm creation does not have the same effect.

    Resolved. Patched the rest of the hosts. Restarted all the toolstacks for good measure. I can move the master role now, and deploy new VMs.

    Actually Alma Linux does have a variant for v2 CPUs so they can run 10.0. Just look for x86_64 v2 on the downloads page.

    Hi Forza, Have you finished migrating the workloads? If you are still looking for an easy migration solution, you can try Vinchin Backup & Recovery. It will replace the driver during migration intelligently.

    @olivierlambert Thank you for the reply. There was a thread on here about the iso not being mounted properly and I commented about having power off the vm and back and it will load the iso. This is specifically true with the 0.4.0 for linux. Image pulled from the XO Hub will not mount the ios if the vm is powered on. There is Yellow Explanation mark next to it. Power off vm and power on vm iso is ok. Reboot vm does not let the ios to work.

    @Pilow Yes, we monitor observability metrics for guest OSes via other means but being able to see this info via the Xen Orchestra web UI along with the other metrics in the Stats tab definitely has is benefits, especially when performing initial troublehshooting or when dealing with groups in our org that only have access to the XO interface and not the other metrics dashboards. Don't get me wrong, I definitely appreciate all of the work that you are all doing to get these tools working and can't wait to start using them in production. I just need to make sure that they work as expected.

    @zpvS9 said in Error installing windows PV drivers 9.0.9137: I have this error too installing the new PV driver, after uninstalling Citrix driver, reboot, execute XenClean, reboot again, it said that an unsupported device is still present. I must uninstall the device by showing hidden device in Device manager and the Windows PV driver now install. So adding this step in XenClean would be appreciated. encountered the same problem with hidden base system that i needed manually uninstall to get the tools to work.

    So first, it's not an XO issue, which helps to diagnose it. Then, it might be a subtle XCP-ng bug indeed.

    said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): @psafont Would designating a new pool master do the same thing? I ran the above command and its had no effect Well, I tried changing the pool master and when VMHost11 was the master I was able to enable HA. Switching back to VMHost13 as the master now so will see how that goes Everything is working as expected/hoped. So for anyone reading through this and wants a TL;DR Issue was related to the pool master setting, changing the pool master to a different host and then back to the original fixed the incorrect settings allowing HA to be enabled

    @lastcmaster Hi, it's a known issue that guest agent versions are not reported after migration or suspend. Other functionalities (poweroff/reboot, suspend, network change etc.) should continue to work normally.
