Re: [Xen-devel] [PATCH V7 00/11] Xen PCI Passthrough

[Tobias Geiger <tobias.geiger@xxxxxxxxx>]

Hi Anthony

thanks for that hint.

I checked out a fresh xen-unstable via hg, compiled it using "QEMU=upstream" , 
checked out qemu.git from where you mentioned and used the resulting qemu-
system-x86_64 binary as "device_model_override" . so far so good.

My Domu (Win7_64) boots fine, but 2 of my 6 passed-through pcidevices dont get 
passed through at all:

libxl: error: libxl_pci.c:756:libxl__device_pci_reset: write to 
/sys/bus/pci/devices/0000:03:00.0/reset returned -1: Invalid argument
libxl: error: libxl_qmp.c:239:qmp_handle_error_response: received an error 
message from QMP server: Device 'xen-pci-passthrough' could not be initialized
libxl: error: libxl_pci.c:756:libxl__device_pci_reset: write to 
/sys/bus/pci/devices/0000:03:00.1/reset returned -1: Invalid argument
libxl: error: libxl_qmp.c:239:qmp_handle_error_response: received an error 
message from QMP server: Device 'xen-pci-passthrough' could not be initialized


The other 4 PCI-Ids (USB Controller) get passed through, but the USB-Devices 
attached to them are "Not Working" according to Windows Device-Manager.

All Devices worked with the old qemu-dm (traditional).

Anything i can do to debug this further?

Greetings
Tobias
