QEMU verhindert Upgrade

Hallo zusammen,

ich wollte gerade auf einem UCS das aktuelle Upgrade auf 4.2 einspielen. Dort läuft ein Windows7 in einer VM welches wohl das Upgrade verhindert. Im Log:

Woran liegt das?

Ich denke mal das spielt auf diesen SDB-Artikel an. Der Link dazu fand sich übrigens in den Release-Notes :wink:
