[Xen-users] modprobe says "Invalid module format" in dom0

[Adam Nielsen <adam.nielsen@xxxxxxxxx>]

Hi everyone,

I'm just attempting to set up Xen for the first time, but I've gotten
stuck at the point of booting the dom0 kernel.  I wanted to custom
compile the kernel (I'm using 2.6.16.16) and this worked, I can boot
Xen with the custom kernel but none of the kernel modules I compiled
can be inserted into the running kernel:

$ modprobe snd-usb-audio
WARNING: Error inserting snd_hwdep 
(/lib/modules/2.6.16.16-xen0/kernel/sound/core/snd-hwdep.ko): Invalid module 
format
WARNING: Error inserting snd_rawmidi 
(/lib/modules/2.6.16.16-xen0/kernel/sound/core/snd-rawmidi.ko): Invalid module 
format
WARNING: Error inserting snd_usb_lib 
(/lib/modules/2.6.16.16-xen0/kernel/sound/usb/snd-usb-lib.ko): Invalid module 
format
FATAL: Error inserting snd_usb_audio 
(/lib/modules/2.6.16.16-xen0/kernel/sound/usb/snd-usb-audio.ko): Invalid module 
format

dmesg reports:

snd_hwdep: version magic '2.6.16.16-xen0 SMP PENTIUM4 REGPARM gcc-3.3' should 
be '2.6.16.16-xen0 686 gcc-3.3'
snd_rawmidi: version magic '2.6.16.16-xen0 SMP PENTIUM4 REGPARM gcc-3.3' should 
be '2.6.16.16-xen0 686 gcc-3.3'
snd_usb_lib: version magic '2.6.16.16-xen0 SMP PENTIUM4 REGPARM gcc-3.3' should 
be '2.6.16.16-xen0 686 gcc-3.3'
snd_usb_audio: version magic '2.6.16.16-xen0 SMP PENTIUM4 REGPARM gcc-3.3' 
should be '2.6.16.16-xen0 686 gcc-3.3'

Which makes me think the modules have somehow been compiled with the
wrong kernel config.  To install the modules I just ran "make
modules_install" from the xen-3.0-testing/linux-2.6.16-xen0/
directory (which is where I ran 'make xconfig' to configure the
kernel.)

Can anyone see what I've done wrong?

Thanks,
Adam.
