PCI passthrough question

PCI passthrough question --> now USB passthrough

Hello all, i have Problems to get PCI passthrough working. I've read many threads about this question but i could not find a solution. The PCI card is DVB-S2 Dual Tuner card Tevii S480:

 lspci: 03:00.0 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.1 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.2 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.3 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.4 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.5 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.6 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller 03:00.7 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller

On the Master Server i have added the following command in the 100.conf file: hostpci0: 03:00.0 But when i try start the vm i get the error "can't reset pci devie '03:00.0' " and the vm didn't start. IOMMU Extensions on the vm are enabled: dmesg | grep -e DMAR -e IOMMU [ 0.000000] Intel-IOMMU: enabled Hardware supports the needed extensions e.g. Vt-d. Any ideas?

lspci:
03:00.0 USB controller: NetMos Technology MCS9990 PCIe to 4âPort USB 2.0 Host Controller

So 03:00.0 is an USB controller (not a DVB-S2 Dual Tuner card)!

Hi dietmar,

that's nearly correct. The Tevii card integrates two USB DVB-s2 receiver on a USB to PCI-e bridge card.

So maybe it is easier to use usb passthrough (instead of pci passthrough)?

Ok dietmar,

I got usb passthrough working - config for the vm:

usb0: host=9022:d481
usb1: host=9022:d482

The man-page of qm made me crazy - but then i found this: http://forum.proxmox.com/threads/7462-Some-Impressions-on-Proxmox-2-0?p=42712#post42712

Thanks!
