Al momento faccio il boot con la seconda GPU, quella che dovrebbe utilizzare l'host, mentre la prima GPU è per il guest.

Code:
#Section "Device"

#    BusID          "07:00.0"
#    Identifier     "Device0"
#    Driver         "nvidia"
#    VendorName     "NVIDIA Corporation"
#    BoardName      "GeForce GTX 760"
#EndSection

Section "Device"

    BusID          "06:00:0"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GT 710"
EndSection


Con questa configurazione di X vedo l'X server sulla seconda GPU.

Ma quando avvio virt-manager, sul secondo monitor la scheda non viene vista , seppur comandata da vfio-pici

Code:

Se non ho capito male, gli ultimi driver nvidia rilevano l'ambiente virtualizzato e si rifiutano di funzionare. :-(

ma nessuno "italiano" che ci abbia provato?
Sono fermo al maledetto errore 43 su windows, che non è altro che un bug volontario sui driver nvidia della stessa nvidia, che vuole vendere le quadro per questo scopo :/

Vedere che altri riescono, e non capire il motivo, mi fa deprimere.... perchè bene o male su linux me la sono cavata quasi sempre :(
