You said you unloaded the driver module for both devices. a) do you have the pcistub module available (kernel config)? For some PCI devices I had to enable both DMA and IRQ remapping in the kernel. The latter is disabled by default. Otherwise: sometimes, especially with older PCI cards, IRQ remapping had to be disabled... at least as module or compiled-in: Bus options (PCI etc.) --> Support for DMA Remapping Devices Bus options (PCI etc.) --> Enable DMA Remapping Devices Bus options (PCI etc.) --> PCI Stub driver [quote] Of course, I unloaded the module of this additional device before trying to passthrough it to the guest.[/qoute] b) Did you try to assign the pcistub driver as printed here: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
