Update:
After waiting long enough the VM starts indeed (strange it need so much time though... like 1/2mins)

And I'm not able to start VM with VNC which prevents me to start the ISO - so either the performance are killed for a reason, or something is still missing.

 

 

This is correct. Will keep looking to see if there is another way.

 

<devices>
  <hostdev mode='subsystem' type='pci' managed='yes'>
    <source>
      <address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
    </source>
    <alias name='ua-test'/>
  </hostdev>
</devices>

<qemu:override>
  <qemu:device alias='ua-test'>
    <qemu:frontend>
      <qemu:property name='x-msix-relocation' type='string' value='bar2'/>
    </qemu:frontend>
  </qemu:device>
</qemu:override>

This is slightly different from what I made:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
      </source>
      <boot order='1'/>
      <alias name='ua-test'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </hostdev>
    <memballoon model='none'/>
  </devices>
  <seclabel type='dynamic' model='dac' relabel='yes'>
    <label>+0:+100</label>
    <imagelabel>+0:+100</imagelabel>
  </seclabel>
  <qemu:override>
    <qemu:device alias='ua-test'>
      <qemu:frontend>
        <qemu:property name='x-msix-relocation' type='string' value='bar2'/>
      </qemu:frontend>
    </qemu:device>
  </qemu:override>

 

In the code you posted, the driver name was removed, it's on purpose?

Maybe try without the driver, was another post I was looking at didn't have that entry.

Ah understood.
I've tried to remove the BOOT ORDER = 1 from the XML, and now I was able to start the ISO:

 

But after 5min is still on the "loading wheel" - instead of showing the "Windows Setup" which should appear after 5-10sec after Loading Files is finished.
i'll try now removing the driver string you mentioned.

Just tried, after the start of the VM (which took exactly the same time), I checked the .xml and 

<driver name='vfio'/>

Was there again.

After a good while, the loading wheel disappeared, but instead of showing the "Windows Installation Setup" its only shows a black screen:

 

I'm really tempted to get another nvme drive (samsung) - but I'm not sure if I will not encounter the same issue... 😐 

 

So in the end I bought a Samsung 990Pro Nvme disk.

With this one the VM works like expected - so I will use the other drive as an extension of my PC and I close this thread.

Thanks a lot for your support and effort.
