UPDATE:
Okay, ich habe mich in anderen Foren schlau gemacht und das Problem ist wohl, dass der VFIO-PCI Treiber zwar beim Start verbunden wird, dieser im Bootvorgang aber wohl wieder vom xhci_hcd überschrieben wird. Es gibt allerdings einen Workaround wie man nach dem Bootvorgang den Controller mit unbind/bind mit VFIO-PCI konnektieren kann. Mit dem Skript von Andre Richter unter
https://github.com/andre-richter/vfio-pci-bind
könnte man das in den Bootvorgang einhängen. Das Skript funktioniert und das Device hängt dann tatsächlich am VFIO-PCI.
So weit so gut...
Nachdem ich aber das Device in die VM eingehängt habe, hat es nicht wirklich Verbesserungen gegeben.
Genauer: Das gesamte System wird beim Boot der VM langsamer und sobald ich die VM schließe, friert wieder der ganze Server ein.
Den ganzen xhci_hcd Treiber kann ich leider nicht blacklisten, weil ich den onboard Controller für das System benötige (z.B. USV)
Ich poste mal ein paar Zeilen der Konfiguration

Bin ich so blind? Ich kann mir das gerade nicht erklären und verzweifele nahezu. Wieso friert sogar der ganze Server ein?
