The /etc/libvirt/libvirtd.conf file is libvirtd's configuration file and contains a lot of interesting options, but some of the most important options are actually located almost at the end of the file and are related to auditing. You can select the commented-out options (audit_level and audit_logging) to suit your needs.
The /var/log/libvirt/qemu directory contains logs and rotated logs for all of the virtual machines that were ever created on our KVM host.

Also, be sure to check out a command called auvirt. It's really handy as it tells you basic information about the virtual...
