[Fedora-xen] Problem assigning a usb or pci port to a domU

[Atsushi SAKAI]

Hi, Pascal

  Our method needs kernel recompilation.

I want to ask you your environment.
1)Do You plan to do it w/ xenguest-install.py?
  (We are not succeeded yet since pciback.hide is not passed to xen0)
or
2)Do You plan to do from compile?
 (We are just using the original xen's buildconfigs/linux-defconfig_xenU_x86_32)
 and Set 
 CONFIG_PCI=y
 CONFIG_XEN_PCIDEV_FRONTEND=y
 for DomU
 and
 CONFIG_XEN_PCIDEV_BACKEND_PASS=y
 for Dom0

For more detail, see the original Xen file of 
linux-sparse/drivers/xen/pciback/Makefile.


Thanks

These parameters are set to "y" in xen0 and the xen documentation says that it is possible to use xen0 in the domains and it might be easier to do than to build from the source. quote "The ``0'' suffixed privileged versions can be used to boot the system, as well as in driver domains and unprivileged domains."
