Hello there,

first of all: proxmox is very nice, good work, i have used virtualbox before.

I have an Asrock 970 Board with an AMD 6 core, BIOS enabled IOMMU and kernel_boot Option "amd_iommu=on".
dmesg show me this:

Code:
[COLOR=#333333]dmesg | grep -e DMAR -e IOMMU[/COLOR]Please enable the IOMMU option in the BIOS setup [COLOR=#333333]AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40
[/COLOR]

My dvb Card (only one Card) has this lspci infos at proxmox host:

Code:
03:05.0 Multimedia video controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
03:05.1 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [Audio Port] (rev 05)
03:05.2 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)
03:05.4 Multimedia controller: Conexant Systems, Inc. CX23880/1/2/3 PCI Video and Audio Decoder [IR Port] (rev 05)

Also, i have all dvb* and card specific modules in the blacklist and set the option
echo "options kvm allow_unsafe_assigned_interrupts=1">/etc/modprobe.d/kvm_iommu_map_guest.conf


if i use the line "hostpci0: 03:05.0" in the the vm.conf, it won't start with parsing error.
With "hostpci 03:05.0" it starts... (hostpci without the zero).

Then in the vm i see with lspci this:

lspci
Code:
00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)
00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II]
00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
00:01.2 USB controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01)
00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03)
00:02.0 VGA compatible controller: Cirrus Logic GD 5446
00:03.0 Unclassified device [00ff]: Red Hat, Inc Virtio memory balloon
00:12.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 03)

Where is my device and where is the "rest" of it ?
