Hi everybody,<br>
<br>
i'am not able to configure a working pci passthrough under f8.<br>
<br>
Here some Parameters:<br>
- Using virsh to manage my guests<br>
- Xen host is running 2.6.21.7-2.fc8xen (SMP) from 15. Feb. 2008
12:39:36<br>
- Virsh version: libvir 0.4.0/ API xen 3.0.1/ Hypervisor 3.1.0<br>
- Guest is setup with virt-install<br>
<br>
XML-Configuration of guest locks like this:<br>
<i><domain type='xen' id='-1'><br>
<name>VM6</name><br>
<uuid>3a84bc19-69fe-370d-8726-508a4714ceae</uuid><br>
<bootloader>/usr/bin/pygrub</bootloader><br>
<os><br>
<type>linux</type><br>
</os><br>
<memory>131072</memory><br>
<vcpu>1</vcpu><br>
<on_poweroff>destroy</on_poweroff><br>
<on_reboot>restart</on_reboot><br>
<on_crash>restart</on_crash><br>
<devices><br>
<interface type='bridge'><br>
<source bridge='br2-dmz'/><br>
<target dev='vif-1.0'/><br>
<mac address='00:16:3e:42:23:56'/><br>
<script path='vif-bridge'/><br>
</interface><br>
<disk type='block' device='disk'><br>
<driver name='phy'/><br>
<source dev='/dev/VolGroup01/lv_comm-01_xvda'/><br>
<target dev='xvda'/><br>
</disk><br>

</disk><br>
<disk type='block' device='disk'><br>
<driver name='phy'/><br>
<source dev='/dev/VolGroup01/lv_comm-01_xvdc'/><br>
<target dev='xvdc'/><br>
</disk><br>
<input type='mouse' bus='xen'/><br>
<graphics type='vnc' port='5906'/><br>
<pci bus='00:04.0' /><br>
</devices><br>
</domain></i><br>
<br>
<br>
After "virsh define" the "<pci bus'00:04.0' />" is not visible in
an "virsh dumpxml".<br>
"lspci" in the running guest shows no pci devices.<br>
<br>
To hide my pci devices from Dom0 i've modified my /etc/rc.d/rc.local as
described <br>
in some articles found on the web:<br>
<i>#!/bin/sh<br>
#<br>
# This script will be executed *after* all the other init scripts.<br>
# You can put your own initialization stuff in here if you don't<br>
# want to do the full Sys V style init stuff.<br>
<br>
<br>
#<br>
# Initialize xen pciback...<br>
#<br>
modprobe pciback<br>
sleep 2<br>
<br>
# AVM FritzCard...<br>
SLOT=0000:00:04.0<br>
# Add a new slot to the PCI Backend's list<br>
echo -n $SLOT > /sys/bus/pci/drivers/pciback/new_slot<br>
# Now that the backend is watching for this slot, bind to it<br>
echo -n $SLOT > /sys/bus/pci/drivers/pciback/bind<br>

Please can somebody help? ANY hints are welcome!<br>
