@olivierlambert thank you for your response.
Here is the /var/log/xensource.log where you can find the error: xensource.log.txt

Can anyone help me figure out what the problem is?
Here is the /var/log/daemon.log: daemon.log.txt

If you need other logs just let me know and I'll attach them too.

@olivierlambert
Thank you for your answer.
If I list PCIs I get the following outpu:

...
04:02.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
...

Is it right, that I have to use '0000:04:02.0' to attach the device to my VM?
What is the meaning of the first '0000:'?
Have you any idea what the meaning/reason of the error can be?

Cannot_add(0000:04:02.0, Xenctrlext.Unix_error(35, "3: No such process"))

Does anyone have any idea why it is not working?

My machine:
Server: DELL T3620 with E3-1245v6 and 16 GB ECC RAM
OS: XCP-ng 8.2

I could not forward a PCI DVB-C card to a VM.
All needed steps for it were already done (see https://xcp-ng.org/docs/compute.html#pci-passthrough

I need to forward the SATA Controller (00:17.0) and the DVB-C card (04:02.0)

The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem.
message: xenopsd internal error: Cannot_add(0000:04:02.0, Xenctrlext.Unix_error(35, "3: No such process"))

It is very strange. I don't have problems to forward the SATA controller to my TrueNAS VM. It works fine. But with the DVB-C card it doesn't work :'-(.
For analysing here is the output of lshw:

I tried already to forward (00:1c.0)(03:00.0)(04:02.0) without success.

Here are the log entries from /var/log/xensource.log:

What can I do else to get it working?
