[Fedora-xen] server migration

[jm-ml]

aloa list,
i have an existing fedora core 1 machine and want to convert this 
machine to a xen-domU on a fc6(7) dom0.
i tried the following:
- create an imagefile and format it.
- rsync the existing machine to the xen-dom0 into the mounted image file
- then i took the existing kernel of a fc6 domU and copied it to the 
fc1-domU

there is a problem during the systemboot and so i think there should be 
better ways to convert the fc1 machine to a xen-domU.
what way would you suggest?

thanks and greetings
jm
