Hello,
when I try to start xend I receive this error:
root@xenized:~# xend start
ERROR Internal error: Could not obtain handle on privileged command
interface (2 = No such file or directory)
Traceback (most recent call last):

Googling seems that I've not booted with the Xen kernel, but It's not my
case:
