[Fedora-xen] How to use xen-pciback
Hi,
I have compiled Jeremy's kernel on Fedora 14 and it turned out that
xen-pciback is compiled into the kernel as a module. So I made a
"xen-pciback.conf" file in /etc/modprobe.d. The problem is that I have
to get modprobe to load before the drivers to the PCI devices I want to
hide are loaded.
So my question is how do I locate the drivers and find the points in the
boot scripts where I can put the modprobe so that it is loaded before
them? I tried lsmod and modinfo but they don't give much information. I
only managed to find the driver for the Intel EXPI9400PT adapter e1000e.
I want to hide the graphics adapter (Radeon 5450), Two USB2.0 ports, the
Intel adapter, the USB3.0 controller and the Audio device, their
assignments on machine are as follows:
pci_0000_00_02_0 (GPU)
pci_0000_00_12_0 (USB 2.0 should give 2 ports)
pci_0000_00_14_2 (Audio device)
pci_0000_00_0a_0 (Intel Adapter)
pci_0000_00_09_0 (USB 3.0 Interface)
but the question is where can I locate their drivers and how can I tap
into the boot sequence so that the xen-pciback driver is loaded
beforehand? The page
http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as...
gives no information about this. It mentions something about "install
skge ... " but it doesn't say where this line is to be put and how you
figure out that skge is the driver to be disabled.
I have set up the machine to init level 3 in the /etc/inittab (my
install of F14 have no upstart targets). The xen-pciback module seems to
be working. Something is wrong with the onboard sound chip. No drivers
have ever successfully initiated it, neither in Windows nor Linux. So it
is marked as an assignable device when looking it up with xm.

Robin.
