Description Steven Haigh 2006-10-30 08:27:12 UTC
Bugzilla #188771 is re-occuring in FC6.

This seems to be an issue again in FC6 (kernel 2.6.18-1.2798.fc6xen).

Related grub.conf entry:
title Fedora Core (2.6.18-1.2798.fc6xen)
        root (hd0,0)
        kernel /boot/xen.gz-2.6.18-1.2798.fc6
        module /boot/vmlinuz-2.6.18-1.2798.fc6xen ro root=LABEL=/
        module /boot/initrd-2.6.18-1.2798.fc6xen.img

I get the following in the dmesg:
Kernel command line: ro root=LABEL=/ pciback.hide=(01:05.0)
Unknown boot option `pciback.hide=(01:05.0)': ignoring

Comment 1 Gawain Lynch 2006-10-30 09:24:49 UTC
Fedora's Xen kernel has pciback built as a module.

See http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module

But also the CONFIG_XEN_PCIDEV_FRONTEND options is not turned on so to make this
work you have to recompile the SRPM and enable it manually.

Can we please have it added to future kernels?

Comment 2 Stephen Tweedie 2006-10-30 11:51:17 UTC
CONFIG_XEN_PCIDEV_FRONTEND should be set in FC-6 configs --- 

$ $ grep PCI kernel-2.6.18-i686-xen.config |grep FRONT

Please reopen if you continue to have problems.
