[PATCH] auvirt: a new tool for reporting events related to virtual machines

[Marcelo Cerri]

I agree that pid and time is a better way for correlation but I was 
coding a solution based on that when I figured out a problem. There's no 
qemu pid in the audit logs. Libvirt (at least the libvirt shipped with 
RHEL 6.2) always logs its own pid to the audit log.

I'll try to discover if there is another way to correlate them or if 
newer versions of libvirt log the qemu pid to the audit log.

Regards,
Marcelo
