I''m trying to hide a tv tuner card from domain0 using pciback. I have
two
problems:
first, I can''t get the pciback feature to work properly; and
second, I don''t know how to specify the equivalent
pci=[''.''] domU setting in
the new XML config files.
My configuration:
AMD 64
xen.gz-2.6.20-2925.11.fc7 (xen 3.1.)
vmlinuz-2.6.20-2925.11.fc7xen
I''ve followed the directions found at :
http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_mo
dule?highlight=%28pciback%29
The tv tuner has no linux driver so there is no need to unbind or add an
install line to modprobe.conf. My modprobe.conf looks like:
>>>>>>>>>>>>>>>>>
alias eth0 forcedeth
alias scsi_hostadapter sata_nv
alias scsi_hostadapter1 pata_amd
alias scsi_hostadapter2 usb-storage
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
# pciback hide devices
options pciback hide=(0000:01:07.0)
<<<<<<<<<<<<<<<<<<<<<<<
My rc.local looks like:
>>>>>>>>>>>>>>>>>>>>>>>
#/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don''t
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
#make sure our pciback module is loaded
modprobe pciback
# the tv tuner (no linux driver so we don''t need to unbind
SLOT=0000:01:07.0
#echo -n $SLOT > /sys/bus/pci/drivers/xxxx/unbind
echo -n $SLOT > /sys/bus/pci/drivers/pciback/new_slot 2>/new_slot.txt
echo -n $SLOT > /sys/bus/pci/drivers/pciback/bind 2>/bind.txt
<<<<<<<<<<<<<<<<<<<<<<<<
Since there is no linux driver for the tv tuner, I have no need to unbind it
from a current driver or have an install line in modprobe.conf.
When this runs the error message I get in /bind.txt is:
./etc/rc.local: line 16: echo: write error: No such device
Doing a listing of /sys/bus/pci/devices/pciback gives:
[root@merlin pciback]# ls -la

Any ideas on how to get the bind operation to work?
Also, does what is the syntax in the xml config file for
pci=[''..'']. Is
there a reference page with all the supported xml tags?
Thanks!
