Hi; I tried posting this on "users" and got no reply, so I'm trying it here.
VirtualBox version: 5.0.20 and its extension pack downloaded from VB site. I am experimenting with VB on an Ububtu host and a Win7 guest, and attempting to pass the PCI bus of my sound card to Win7. The card is a Echo Gina 3G, which is properly detected and working on the host: [#]>lspci 04:07.0 Multimedia controller: Motorola DSP56361 Digital Signal Processor (rev 01) Board is Gygabyte 970A-UD3P with IOMMU enabled in BIOS and working on the host: [ 1.166869] PCI-DMA: Disabling AGP. [ 1.166951] PCI-DMA: aperture base @ f8000000 size 65536 KB [ 1.166959] PCI-DMA: using GART IOMMU. [ 1.166962] PCI-DMA: Reserving 64MB of IOMMU area in the AGP apertur Applied the proper parameters to the guest: sudo VBoxManage modifyvm Windows7 --pciattach 04:07.0 When I start the VM, I get this: kernel: [ 802.860462] vboxdrv: ffffffffc1003020 VMMR0.r0 kernel: [ 803.220420] vboxdrv: ffffffffc042d020 VBoxDDR0.r0 kernel: [ 803.240172] vboxdrv: ffffffffc0008020 VBoxDD2R0.r0 kernel: [ 803.334353] VBoxNetFlt: attached to 'enp3s0' /fc:aa:14:9d:46:f0 kernel: [ 803.366486] vboxpci: detected device: 1057:3410 at 04:07.0, driver snd_echo3g kernel: [ 803.372298] pci-stub 0000:04:07.0: claimed by stub kernel: [ 803.372364] vboxpci 0000:04:07.0: vboxPciOsDevInit kernel: [ 803.372420] vboxpci 0000:04:07.0: region 0: mmio fe100000+1048576 kernel: [ 803.372442] vboxpci 0000:04:07.0: got irq 21 kernel: [ 803.377131] vboxpci 0000:04:07.0: reg=0 start=fe100000 size=1048576 kernel: [ 803.383887] vboxdrv: ffffffffc00f0020 VBoxEhciR0.r0 kernel: [ 804.778262] device enp3s0 entered promiscuous mode kernel: [ 804.778297] vboxpci 0000:04:07.0: PCIRAW_POWER_ON ------ this is strange since IOMMU is working on the host ------ I also got "no IOMMU found" once kernel: [ 805.787454] vboxpci 0000:04:07.0: cannot attach to IOMMU, no domain kernel: [ 813.422771] HPET: Using timer above configured range: 3 kernel: [ 813.422778] HPET: Using timer above configured range: 3 kernel: [ 813.422896] HPET: Using timer above configured range: 3 kernel: [ 813.422901] HPET: Using timer above configured range: 3 kernel: [ 829.202302] vboxpci 0000:04:07.0: reg=0 start=fe100000 size=1048576 kernel: [ 829.209739] vboxpci 0000:04:07.0: reg=0 start=fe100000 size=1048576 The guest detects the board and installs its driver, but the board doesn't function and its leds go crazy.
