I'm a student, engaged in a project in which QEMU is a candidate to be used to make some studies about IO usage etc.

I need to track the IO requests made to the block devices (e.g. HDD, SSD, etc.). I check the source code but I was confused. What I want to know is that when an IO request is made, find out that which on of the VMs has made that request. I'll thank you if you help me on this issue.

Sincerely Yours,

Aarian
