    ***GUIDE*** Passthrough Entire PCI USB Controller

    in VMs

    Posted

    hello guys. Im having some problems passing through a USB pcie card (http://www.amazon.com/gp/product/B00FPIMICA?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00)

     

    i have attached a usb bluetooth device in the pcie card that i want to passthrough and it shows that is in bus 003:

     

    Bus 003 Device 003: ID 0a5c:2198 Broadcom Corp. Bluetooth 3.0 Device

     

    this is the result from readlink /sys/bus/usb/devices/usbX

     

    root@Tower:~# readlink /sys/bus/usb/devices/usb1
../../../devices/pci0000:00/0000:00:14.0/usb1

    my 2 main questions are:

     

    1- do i need to passthrough all the devices currently on group 7? if so, how do i make sure that all those devices are not critically importat for unraid to properly work? (my unraid usb is on bus 001)

     

    2- which one is the right address for my bus 003? (as it shows ../../../devices/pci0000:00/0000:00:1c.3/0000:04:00.0/0000:05:05.0/0000:08:00.0/usb3)

     

    PD: I'm passing it through to use it with El Capitan Virtual Machine.

     

    thanks in advance for any help that can be provided. suggestions and/or corrections are very welcome.

     

    Edit: I have figured it out.

     

    First I had to enable the option "PCIe ACS Override" on VM Manager under settings. Second, I was using the wrong method to Pass it through because I'm using this method in a q35 machine (Mac OS X El Capitan). I was using the Hostdev method and I needed to use the qemu:arg method.

     

    Wrong (Hostdev method):

    <hostdev mode='subsystem' type='pci' managed='yes'>
<driver name='vfio'/>
<source>
<address domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
</source>
</hostdev>

     

    Right (qemu:arg method):

        <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=08:00.0,bus=root.1,addr=00.1'/>

     

    Note that the addr=00.1 because in the addr=00.0 i have my GPU passed through.

     

    Is now working like a charm. Hope it can help somebody.
