libvirt log messages
By default, libvirt log messages are stored in the system journal. You can specify a different location in the libvirt configuration file at /etc/libvirt/libvirtd.conf. For more information, see libvirt.org/logging.html.
QEMU log file of a virtual server
/var/log/libvirt/qemu/<VS>.log, where <VS> is the name of the virtual server.
Console log file
If the log element is specified in the console configuration, the log file attribute indicates the console log file.
Example:
The following console configuration specifies the console log file /var/log/libvirt/qemu/vserv-cons0.log:
<devices>
    ...
    <console type="pty">
       <target type="sclp" port="0"/>
       <log file="/var/log/libvirt/qemu/vserv-cons0.log" append="on"/>
    </console>
</devices>
