Re: [Xen-users] PCI Passthrough of iwlwifi adapter into Windows HVM failed to start

Quoting "John Mok" <a9121431@xxxxxxxxx>:


I am using Xen 4.4.1 on Debian Jessie on Lenovo ThinkPad X250.

I succeeded to passthrough the Intel AC 7265 adapter to the Windows
HVM. However, when I installed the Intel driver (with embedded
firmware), the device failed to start with code 10.

I tried to switch between GPL PV driver and SuSE VMDP 2.2, and it made
no difference.

I hope someone could point me how to pass through and make the Intel
AC 7265 adapter working on the Windows HVM.

Thanks a lot.

Just to confirm, are you certain that the driver in question really does work when it is running on baremetal or some other virtualization? I.e. this problem really is Xen related, and not a problem with the driver, OS, or device itself?

I'm just guessing here, but does dmesg/journalctl have anything to say on the Dom0 side? In particular, an error about the driver attempting to write to read-only configuration space could indicate that you need the "permissive=1" flag.
