You didn't tell us how it crashed, but...

The two devices above seem to be wrong, when compared to the Xen configuration
file below. It looks like you want something like:
<devices>
<disk type='file'>
<source file='/data/images/nagin/c1/ken-30/fedora.fc8.img'/>
<target dev='xvda1'/>
</disk>
<disk type='file'>
<source file='/data/images/nagin/c1/ken-30/fedora.swap'/>.
<target dev='xvda2'/>
</disk>
If that doesn't help, please tell us how it crashes, exactly, and give the
console output from the guest (if it gets that far).
