[Xen-users] Pciback in Fedora 8 domU - Is it not working?
I cant seem to get the pcibacked device to come up in the F8 domU. I get these messages in dmesg: PCI: Fatal: No config space access function found PCI: setting up Xen PCI frontend stub Setting up standard PCI resources ACPI: Interpreter disabled. Linux Plug and Play Support v0.97 (c) Adam Belay pnp: PnP ACPI: disabled xen_mem: Initialising balloon driver. usbcore: registered new interface driver usbfs usbcore: registered new interface driver hub usbcore: registered new device driver usb PCI: System does not support PCI PCI: System does not support PCI Any ideas on what to do? Thanks Chris _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The standard F8 xen kernel has CONFIG_XEN_PCIDEV_FRONTEND=y, and thus is built in, not a module. (You''ll notice this setting is completely missing in F9 :-( ). Make sure that your domu config has a line of the form pci=[ ''0000:0b:00.0'' ], and that on startup of the domu, you see in /var/log/messages a line of the form: Jun 14 13:05:15 Insp6400 kernel: pciback: vpci: 0000:0b:00.0: assign to virtual slot 0 and in dom0, the directory /sys/bus/pci/drivers/pciback has a link named after your device id. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
