Default Xen 3.0.3 + Debian - No modules available in VM

Hi,

I trtried to install Xen 3.0.3 with the help of Falkos howto on my machine – everything worked out fine except to load modules on the virtual machine.
Here's what I got:

Code:
Fily:~# cat /proc/modules 
Fily:~# modprobe quota_v2
Note: /etc/modules.conf is more recent than /lib/modules/2.6.16.29-xen/modules.dep
modprobe: QM_MODULES: Function not implemented

modprobe: QM_MODULES: Function not implemented

modprobe: Can't locate module quota_v2
Fily:~#
And here is some other stuff what I'm a little unsure about when I start a virtual machine. I don't really nowif I have to worry about or if I can ignore those messages which I coloured red:



Code:
Xen-Daddy:~# xm create -c /etc/xen/vm01-config.sxp

Got it - first and biggest problem fixed ....


something in the debootstrab faild. The programmes modutils and module-init-tools where missed. I easily installed them via:

Code:
aptitude install modutils module-init-tools -y
I hope it will help somebody else ;-)

But what about the PCI Stuff etc ... ?!


Thx

Leo

Isn't it possible to let the hostsystem handle PCI cards like a tv card to stream TV with for example VideoLanServer ?... I don't need that at the time, but I'm sure I've heard that xen is able to share PCI Cards with its guestsystems.


And waht about the high and low memory messages on top?
