I would like to assign a pci tv-card to a virtual machine. Unfortunately it shares its IRQ with two other devices (an UHCI USB controller and the P-ATA controller. Furthermore it is behind one pci bridge together with an onboard firewire controller which shares its interrupt with another USB controller.
I hava unbound all of these devices and loaded the stub driver.
The command line is:
kvm -hda /var/vm/vm.img -net none -pcidevice host=03:00.0 -pcidevice host=00:1a.0 -pcidevice host=03:03.0 -pcidevice host=01:00.0 -pcidevice host=00:1d.1 -serial stdio -nographic
and it fails with
Failed to assign irq for "00:1a.0": Input/output error
Perhaps you are assigning a device that shares an IRQ with another device?
Failed to deassign device "00:1a.0" : Invalid argument
Failed to initialize assigned device host=00:1a.0
depending on the order of the -pcidevice options
The question is: is it possible at all to assign devices under these conditions?
Thanks for your help,
