Okay, i found my mistake on my own. The mistake was a wrong configured lo
Interface and the wrong defined nameservers In this environment. This causes
my DomU running impossible slowly (5 minuttes to open mc :-) ) A correction
of this and all works fine now.

i created a domU MAchine (debian Sarge)on an lvm patition under Xen3 with
actual kernel 2.6.12. This worked verry well and fast. I decided to move
this domU to an other machine running Xen 2.0.7. After copying the lvm on
this machine and creating the config file I booted this domU up with Kernle which seems to be the most actual kernel fpr xen2.0.7 in a domU. 

My Problem ist that the domU is verrrrry slow it need more than 4 Minutes to
boot into a debian base system. And starting an application is quiete
impossible with this week performance. 
To be shure that xen dom0 works fine I created a new domU on this machine
with an lvm drive an a debian base system. This works verry well an fast...

Has someone any idea what causes this problem? Or how I can fix it? 

Here are my logfiles:
