[Xen-users] Ubuntu 11.10 and Xen 4.1.2 (i386)

[Sebastian Biedermann <biedermann@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Dear List,

I have a problem running Xen 4.1.2. und my Ubuntu 11.10 (i386).
I use the included Linux kernel 3.0.0-13-generic-pae which supports dom0.
I compiled and installed the Xen from sources because I need some 
special features..
After reboot, xend is not running...

~# xm info
Error: Unable to connect to xend: No such file or directory. Is xend 
running?
~# cat /proc/misc | grep xen
56 xen/gntdev
57 xen/evtchn

~# lsmod | grep xen
xen_netback 27180 0 [permanent]
xen_blkback 22624 0 [permanent]
xen_gntdev 13295 0
xen_evtchn 12967 0
xenfs 17877 1

~# ls -la /dev/xen
drwxr-xr-x 2 root root 80 2011-11-23 17:09 .
drwxr-xr-x 15 root root 4220 2011-11-23 17:09 ..
crw------- 1 root root 10, 57 2011-11-23 17:09 evtchn
crw------- 1 root root 10, 56 2011-11-23 17:09 gntdev

~# cat /proc/xen/capabilities
control_d

That looks okay to me, please correct me if IÂm wrong...
But xend is not running..

When I start xend using the command /etc/init.d/xend start the network 
connection
gets immediately interrupted and stays broken.

Can anyone give me a hint?
Thank you !!!
