Description Chris Lalancette 2009-05-19 11:37:01 UTC 
Description of problem:
The hardvirt patches that went into the 5.4 beta kernel are causing a new message to be printed to the console every time a domain is started:

(XEN) Weight assignment 2 - w 1 h_virt 0
(XEN) Weight assignment 2 - w 1 h_virt 0

The solution is simple; just remove that printk() from common/sched_credit.c, since they don't really serve a hugely useful purpose.
