@olivierlambert thank you Olivier. Indeed you are right, we need to change also the max vcpu limits in advanced. [image: 1653224017629-0cc87b88-9234-4671-bf18-4280acd996cd-image.png] Then is booting normally.

Hey thanks for the feedback

Sure, Another thing is that included iPXE is a version that does not support multipath SAN boot (I guess it would be nice to update it)

@AndreS That’s great thanks very much AndreS!

If you have a valid XOA license, then you always have the option of opening a support ticket. Anything unusual / different about this VM? How many disks attached? P.S. I assume that you're aware that Windows 2008 isn't officially supported any longer.

@alejandro-anv I have had problems like this on my NFS and iSCSI SR's previously. One thing that might help is to shutdown the VM's before doing a re-scan. If my memory serves me, it does a different kind of coalesce (online vrs offline) and this has a better chance of success. Also, be aware that from the time you re-scan and the time it actually starts to do work on the drives is 5 minutes. When I have a problem like this, I normally ssh into the pool master and tail the logfiles to watch it work. IE: tail -f /var/log/SMlog | grep SMGC Its boring.. But.. it gives me a bit of comfort between prayers 8-)

@olivierlambert said in XCP-ng 8.2 hangs on shutdown: Yes that's what he said (ISO SR in a VM) Ah yes. I see that. Oups.

@Danp I will try to install latest updates

OK @olivierlambert was correct, I mistakenly had enabled secure boot previously before the update so it was already on when I did the reboot. Just tested things in my home lab again and they did NOT change from disabled to enabled, so good to go! Thanks!

@Kaiz I am very much guessing here, but: I don't think you're looking at a single card in this case. Rather must be a switch of some kind involved, which translates between PCI and PCIe and also allows more than one PCI device to be connected to the PCIe bus. And you'd have to remove all devices from the Dom0 (host) add all devices to the DomU (guest) VM (as a list in a single command) lshw may help you figure out the bus topology and device IDs, although none of the Linux tools seem to come close to how HWinfo displays things on Windows. It should definitely help you see things more clearly on the Windows VM, once devices arrive there. If you have any other device, say a spare NIC to test on first, you may be able to save yourself pulling from pulling your hair out.

@olivierlambert https://github.com/cert-ee/cuckoo3 you are right. Seems that they are preparing next version. I don't know what hypervisors will work with this. Edit: qemu and kvm.

Hello, Can you with a support client for XCP-ng? (like XO). You can also use xe to see the output.

@stormi Hi, its good to know. Thanks for the answer i think now its solved and explained.

@Heady Update - I have been able to make progress. (1) I have been able to get XO version 5.80.0 appliance installed. For some reason the automated web deployment method didn't work. Couldn't work out why. (2) Had to reinstall xcp-ng again on the new host. (3) Using XO appliance - had to add a number of interfaces prior to attempting to add to the pool. (3) Using XO appliance - have been able to add the new host to the pool. (4) Took a few reboots and manual powercycles to get the new host integrated into the pool and recognized within XO appliance. Shutdown/reboot would hang and not complete. (5) The SRs had to be connected / disconnected / connected from the XO Host-Storage tab for them to be online and accessible. Couldn't use connect to all hosts from the Pool-Storage tab. (6) Then finally success in moving VMs from the old host to the new host. Phew... half-way there.

@kulmacet Can you recreate this with other VMs, or just this specific oracle linux VM? I would spin up a new debian VM for example and shut this problematic VM off, and see if the issue happens with this VM as well. Outside of that, it's really looking like a hardware issue. Also, double check the ILO and BIOS firmware are at the latest. I can almost guarantee it shipped with ancient versions, and many issues like this have been patched relatively recently.
