Virtlib logs end in the way you see, only when i kill the qemu process
then it starts logging and it is possible to connect remotely with
virsh.
Until the qemu process is active you can not use libvirt.
In the following libvirt log file find all that happens when killing
the qemu process, after the line

Command result 0, with PID 970
