vfio-bind location

[joelones]

Is vfio-bind a script that is no longer part of rc?

 

-bash: /usr/local/sbin/vfio-bind: No such file or directory

 

I'd like to pass in a usb controller.

You shouldn't need to do the vfio-bind process any more.  unRAID takes care of that automatically now.  I know I've never had to use it to pass through a network card.  I could swear I didn't for a USB card either but I don't currently have that setup.  I can try it out this weekend if you want me to as I think I have a 3.0 USB card I could put in and test out on a Windows VM.

So what's only needed is the appropriate line in the xml? This is what I have:

 

    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=00:16.0,bus=root.1,addr=02.0'/>

 

If I don't do the vfio-bind thing, I get an error:

It sort of seems individuals are still using this method as per the latest posts here: http://lime-technology.com/forum/index.php?topic=36768.msg402777#msg402777

I just used the instruction here: http://lime-technology.com/forum/index.php?topic=38259.0 for my nics when I pass them through.  I was going to do the same this weekend for USB card and MB USB hub and see if it works.

Oh thanks, going to give that a go.

 

Edit:

Yep, works as well.
