    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 ?

    If i recall from my migration I belive thats all there is to it. I know the docs mention about doing a test migration but mine just migrated and it just worked as you stated after making the needed adjustments. Let other chime in but i think you are good to go. And you could delete the snapshot from the vm.

    @benapetr Good news, seems like the latest version for SM will implement vdi_revert which should work nicely with Ceph RBD. The only thing now is to have the newer Ceph kernel drivers in XCP-ng since the current driver is very old... (v12 I believe, we're now at v20, soon v22)

    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.

    @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.
