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 enable
debug-threads if supported.
