In lnet/libcfs/{tracefile,debug}.c is the interface for printing log
messages.  For Linux this ends up storing the message in the Lustre
kernel debug log, and via printk() to the console if the severity is
high.  It would be relatively easy to change this code to use something
other than prink() inside XEN.

Cheers, Andreas
