Comment 40 for bug 218126

janevert,

sorry that was everything i got from xen.. the machine wasn't started at all and the bootprocess was cut off as well at that point.
I changed back a test-setting in the hwclock-scripts in the VM-root, so now there is a little more:

now xen states that the machine is already present, but it isn't visible in 'xm top'
