ib_logfile0 and ib_logfile1 got deleted
You have three(3) options
OPTION #1 : Redo the XtraBackup with the Proper Preparation Steps
The preparation step was meant to carry the logs along for the ride. You must go back and run the backup again.
OPTION #2 : Play with Forced Recovery
Rather that reinvent the wheel, please see my post
The InnoDB log sequence number is in the future
OPTION #3 : Run Multiple rsyncs
This is rather risky, but you can run rsync multiple times against the live MySQL instance until two consecutive rsyncs take the same amount of time. Then, shutdown mysql on the source, run one more rsync. Then, after due diligence, startup mysql on the new server.

Give it a Try !!!
