Hi,

>And I got trouble in DomU configuration.
I solved this problem.
I made xen with KERNELS="linux-2.6-xen0 linux-2.6-xenU".
However, CONFIG_PCI/CONFIG_XEN_PCIDEV_FRONTEND is not set
in buildconfig/linux-defconfig_xenU_x86_32.
I modified this file manually.
p.s. In linux-defconfig_xenU_ia64, CONFIG_PCI had been set to 'y'.
I don't know why CONFIG_PCI turned disabled in linux-defconfig_xenU_x86_32.
cheers,
