You should have a PCIe slot that does not sit behind a PCI-PCI bridge. > As much as I'd hate to solve a problem with the application of money... :( If you just want _one_ tuner to go to the guest, you should be able to do that by unbinding the other devices and giving the guest just the one usb controller (assuming just assigning the usb device itself is hitting usb/qemu stack limitations). The trick is to be sure to unbind any host devices that are sharing interrupts with the one device you want the guest to have. With USB controllers you just have to be sure you know which ports they map to so you don't kill a keyboard, mouse, external disk, etc... > (OT question, on mailing lists should I use Reply All or just reply > and change the To address to kvm.vger.kernel.org?)
