I'm hiding the pci-device in the dom0, capturing it in the domU, and rceive the following lines in /var/log/syslog of the dom0 after a reboot: ======================================================================= Aug 8 00:04:49 localhost kernel: pciback 0000:00:1d.7: Driver tried to write to a read-only configuration space field at offset 0x54, size 2. This may be harmless, but if you have problems with your device: Aug 8 00:04:49 localhost kernel: 1) see permissive attribute in sysfs Aug 8 00:04:49 localhost kernel: 2) report problems to the xen-devel mailing list along with details of your device obtained from lspci. ======================================================================= I'm not quite sure what I'm expected to do in the /sys-tree: root has write-permissions all the way down the branches. I'm using the stable version of the xen-hypervisor 3.0.3-0-2 (debian). I kind of *need* this functionality and would be very grateful for any kind of help or hint. Thanx in advance, Bests from Vienna/Austria Matthew A. Wolf pS.: THANKS a whole lot for such a fine piece of software!
