    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
    [COLOR="Red"]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[/COLOR]
    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

    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?
