How to hide PCI device prior to passthrough


Recommended Posts

I have a Plus copy of UnRaid, which has a 12 drive limit.

 

In my server setup I need to passthrough a LSI 9201-16i HBA to a windows VM. The problem is that the HBA card has 16 drives attached to it, and i can't start the array (and hence pass through the PCIe card) because UnRaid is throwing an error saying that I have too many drives, and the array can't be started.

 

How do I deal with this situation? I don't want unraid to see that PCIe HBA, but I do want unraid to pass it through to a VM.

Ahh thanks!
vfio-bind is what I was looking for.

 

How convenient that this feature is added just as I need it :)

 

Binding a device have been available since a long time. They just added a new method that didn't involve using the syslinux.cfg.
