at boot stage, the VPS is accessed via a web based virtual console which looks like a emulated VGA display from Qemu. Later in the dmesg there is no emulated graphics adapter found. There is a device "virtio2" which seems to identify as a console device:

```
[....] virtio2 at pci3 dev 0 function 0
[....] virtio2: console device (rev. 0x01)
[....] virtio2: autoconfiguration error: no matching child driver; not configured
```

And there is also an emulated com0 interface present, which seems to be useless as I cannot access it from outside.

As a test I switched off the virtio module via userconf and booted it. Here the boot comes at least up to the prompt for the root filesystem device (of course, since no virtio exists any more, the block devices are also no longer recognized).

I can't really explain why the boot loader and the kernel messages can write to the virtual console, but later in the run no corresponding graphics adapter is found...

Kind regards
Matthias
