Xen users - Feb 2012 - blocked domain

Hi,

with virt-manager I have reached the following state:

# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  3005     1     r-----   6236.5

The installation from an iso image did not start, how can I start it
from this blocked state?
