Hello List,
I am a graduate student trying to learn about virtualization. I wanted
to understand if there is any way to tell about resource consumption
of guest through Qemu ? e.g. if guest starts doing something cpu
intensive, would qemu be aware of that ? or is there a way to detect
that from qemu ?

I assume your talking about a KVM quest rather than a system emulated
guest within QEMU? KVM guests will appear as normal user-space tasks to
the host OS so your normal top/htop/iotop tools will show activity
associated with that guest.
I don't think qemu directly monitors CPU utilisation but I could be
wrong. Other information is available though - see
docs/virtio-ballon-stats.txt for example.
Things that trap to QEMU (i.e. hardware access, virtio) however can
certainly be tracked. The the guest is in a pure CPU loop then qemu
won't know about it until the next event it has to deal with.
