Audit log 1

Description of problem:
The targeted SELinux policy prohibits xend from starting.

Version-Release number of selected component (if applicable):
xen-4.1.0-2.fc15.x86_64
selinux-policy-targeted-3.9.16-23.fc15.noarch

How reproducible:
Every time

Steps to Reproduce:
1. Boot with SELinux enforcing its targeted policy
2. Start xend
  
Actual results:
Xend fails to start, as noted in the log below. Although xend fails to start everytime, the audit log cycles between two possible outputs each time I try to restart xend. These are attached as 1.log and 2.log.

TypeError: ord() expected a character, but string of length 0 found

Expected results:
Xend should start.

Additional info:
Setting SELinux to permissive mode allows xend to start. I have to restart it twice to get it to finally start. This is probably related to the comment about the two audit log outputs above.
