I'm wondering about this tool. It runs fine. But I thought you were wanting to do 
some more sophisticated analysis of events. For example this is the current 
output:

$ ./auvirt --file ../../../virt-audit.log
Total records:      6
Virt records:       6
Resource records:   4
Machine ID records: 1
AVC records:        0
Operations:
  Start:            1
  Stop:             0
Considered time:
  Start:            Tue Dec 20 09:33:01 2011
  End:              Tue Dec 20 09:33:01 2011

This is not much different than what can be reported by ausearch/report with the 
new uuid and vm search fields. Also, testing with the uuid number doesn't seem to 
get any hits. But using the vm name does. 

I plan to add a very basic virt report to aureport soon. I was wondering if the 
above is all anyone really wanted to see? I would think that perhaps you want 
some info about start/stop assignment of resources, changes in resources, and 
perhaps MAC or anomaly events related to a vm. But laid out like the aulast 
program.

boot  vm-name   time  (total runtime)
resource  what-kind  old-value  new-value  time (total time assigned)
avc   access-type  obj  results  time
shutdown  vm-name  time

and there might be other audit events associated with a vm.
