[et-mgmt-tools] converting full to para

[Joey Boggs]

I was using this process a few months back. Most likely what's happening 
is that it's missing the disk controller modules in the in initrd so 
it's not able to find your logical volumes. You'll will need to update 
your  /etc/modprobe.conf to use the paravirt modules (xennet/xenblk) 
then rebuild the initrd. Should boot at that point.
