[Qemu-devel] [PATCH v4 2/2] qemu_kill_report: Report PID name too

[Michal Privoznik]

When qemu is being killed, its last words are:

2016-08-31T11:48:15.293587Z qemu-system-x86_64: terminating on signal 15 from 
pid 11180

That's nice, but what process is 11180? What if I told you we can
do better:

2016-08-31T11:48:15.293587Z qemu-system-x86_64: terminating on signal 15 from 
pid 11180 (/usr/sbin/libvirtd)

And that's exactly what this patch does.
