My experience with it was that it was a lot slower than my (not very good) emulator, I imagine because I was some using it wrong somehow (? qemu is high quality software). And also as I was using it I was managing to corrupt state somehow in a way that meant it didn't end up ultimately helping with the thing I was trying to debug.
