Good afternoon @olivierlambert !)
Most likely caused by the virtual machine itself. Because all the other VMs were fine) and the VMs are all on the same disks. According to the load and smart physical disks, everything was normal.
Also, when restarting the problematic virtual machine, the problem did not disappear. We didn't want to recover from backup, because it would take a lot of time and it was decided to move the virtual machine to another physical disk.(After that, the VM load problem disappeared)

@Andrew Good suggestion, might as well pick some up, thanks!

@Andrew thanks for your reply. I have more than enough cores and memory slots for one CPU so I guess I’ll put one of the CPUs in the drawer.

@andyhhp well I took way longer than I said I would, but I promise I still wanna work on this lol.

Here is the link to the thread that shows my crash reports. As a reminder, this crash happened on this host randomly and didn't seem directly related to PCI passthrough, or at least not the driver install part which I was having issues with.

@Darkbeldin let hope I am lucky

@olivierlambert thank you Olivier. Indeed you are right, we need to change also the max vcpu limits in advanced.

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.
