Are your images fully virtualized or paravirtualized? You may have to
play some kernel duplication games with paravirtualized.

Can you just do an OS update to CentOS 5 or FC 7, rather than having to
install from scratch? And can you back up your images somewhere for
safety's sake before you update?

Thank you for your answer!

The images are fully virtualized.
An update is not possible, cause now i use FC6 i386, and i have to install "centos5 with 64 Bit support" (could this change from i386 to 64Bit support be also a problem for the images to start?)... i made already a backup of /etc/xen/* and for the images. do i need to attend something else?

Thank you!
