QEMU (somewhere around 2.0) added a new sub-option to the -name flag -name debug-threads=on
This causes the naming of individual QEMU threads to be helpful; e.g. 'CPU/KVM 0' or 'migration' these show up in top once the H key is pressed, and also show up in a core dump, making it easy to figure out which thread is which.
The following 2 patches add a capability check and a qemu-conf key to enable debug-threads.
Is there any reason against enabling this unconditionally? It sounds like a nice thing to have if possible so I'd just always enable it if QEMU supports that...
That would be fine for me, I just wanted to be as careful as qemu is. They were probably thinking some monitoring tool could be confused. I suppose in libvirt case, there should not be furthere such monitoring, and libvirt is not confused. So why not? Keep the first patch, simplify the second? thanks -- Marc-André Lureau
