Hey folks,

it took me two hole days to come so far: xen kernel starting, xen tools are working etc..
So now I want to create a new domu guest. I created it with�xen-create-image --hostname=alfredo --size=8Gb --dist=lenny --memory=512M --ide --dhcp.
But when I am trying to start my new mashine I get the following error:�

xm create alfredo.cfg -c

Using config file "/etc/xen/alfredo.cfg".
Error: Device 2049 (vbd) could not be connected. Path closed or removed during hotplug add: backend/vbd/3/2049 state: 1

Okay. Googled for two hours tried everything like max_loop=64 etc but nothing helped.
One thing I find suspicious is teh following log entry:

kernel-provided name 'evtchn' and NAME= 'xen/evtchn' disagree, please use SYMLINK+= or change the kernel to provide the ...

What does it mean and how can I fix it if necessary?


So here are my releveant logs:

cat /dev/xen
