There should be enough work to do a 12 week project.

I'm not sure how involved this will be.  Perhaps it can be combined
with related tasks to expand the scope to a 12 week project.

I agree, that storage driver job cancellation and progress reporting
is a good project idea.  The scope fits and it is a useful feature to

They can start with scrub where libvirt has 100% control.  Then,
depending on their level of skill and time remaining, they can tackle
the QEMU commands.

The next step is to find concrete problems for the project
description.  This will allow students to begin looking into the
libvirt code so they can come up with a plan for their work.  It's
best if you can point out the virsh commands or virt-manager methods
that current block or are uninterruptible.

Not sure how much work is necessary here but it could also be a good
project idea for GSoC.
