I don't know see this as a configuration problem, which is why I'm
sending to the xen-devel list...



I have been trying to get ztdummy to load under domU running a 2.6
kernel (2.6.16), which ztdummy defaults to use RTC. However, domU
doesn't have access to the RTC (in particular IRQ 8) directly and
ztdummy fails to load without RTC.

asterisk-12:/lib/modules/2.6.16.29-xenU# modprobe -a ztdummy
rtc: IRQ 8 is not free.
WARNING: Error inserting rtc
(/lib/modules/2.6.16.29-xenU/kernel/drivers/char/rtc.ko): Input/output error
ztdummy: Unknown symbol rtc_register
ztdummy: Unknown symbol rtc_unregister
ztdummy: Unknown symbol rtc_control
FATAL: Error inserting ztdummy
(/lib/modules/2.6.16.29-xenU/misc/ztdummy.ko): Unknown symbol in module,
or unknown parameter (see dmesg)
WARNING: Error running install command for ztdummy

When I tried to approach this differently (using the uhci_hcd), I notice
USB support isn't available to domU either...

cd /usr/src/xen-3.0.3_0-src/
make linux-2.6-xenU-config CONFIGMODE=menuconfig KERNELS="linux-2.6-xenU"

Does anyone know why the list is empty  Device Drivers ---> USB Support?
All I can see is USB Gadget Support, I can see the list in the dom0 config:

cd /usr/src/xen-3.0.3_0-src/
make linux-2.6-xen0-config CONFIGMODE=menuconfig KERNELS="linux-2.6-xen0"


I can understand why RTC support to dom0 is not available but is there a
way to provide USB support to domU?


I have not subscribed to either list yet, please respond to heison@chak.ca directly.

Thanks
