PCI Pass trough - parallel card

[tmo-nid]

Hi all,

I search to install a PCI parallel card on a KVM based virtual machine. But without success...

I followed different Howto and post (http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM)

I added amd_iommu=on to my grub.

dmesg | grep AMD-Vi
AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40
AMD-Vi: Initialized for Passthrough Mode
AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40

My parallel card :

lspci -nn
01:00.0 Parallel controller [0701]: NetMos Technology Device [9710:9900]

and

echo "9710 9900" > /sys/bus/pci/drivers/pci-stub/new_id 
echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind 
echo 0000:01:00.0 > /sys/bus/pci/drivers/pci-stub/bind

I tried several solutions as use the following command in guest command interface : device_add pci-assign,host=01:00.0,id=mydevice

and also directly in my configuration file by adding :
- hostpci: 01:00.0 or args: -pcidevice host=01:00.0

In all cases, I have an error

Device 'pci-assign' could not be initialized
