I'm having a decent amount of trouble getting pciback to behave the way I'd<br>
like it to.<br>
Originally I found xen-pciback was compiled as a module and not directly<br>
into the kernel, ruling out use of the boot-time argument<br>
xen-pciback.hide=(blah) ... so I recompiled my kernel, incluging pciback<br>
directly into the kernel.<br>

Could you pass the option to the module by creating a file in /etc/modprobe.d/ to supply the options to the module (the modprobe.conf explains the format)? I think those files get copied over to the initramfs when you install a kernel so they should still be used even if the module is loaded early in the boot process.<br>
<br>
Incidentally, you seem to be using xen-pciback in one place and pciback in another. With a recent Fedora based kernel I would expect you would need to use xen-pciback throughout.<br>

I made sure I specified xen-pciback instead of the older pciback ... not really sure which line in the configuration it goes on in /etc/default/grub - leaving it on the XEN line for now.

After reboot, none of the devices are hidden from dom0. I can forcibly unbind them from dom0 with a script, but that seems messy and some of the pci devices don't seem to like it (sata controller for example)</div>
