Does KVM support or plan to support differencing disks (where there is a
read-only source disk, and each person running a virtual machine can
save block-level changes that their virtual machine is making to the
disk in a separate "differencing" image)?

If so, can somebody suggest how I may make use of this feature (i.e.
building the newest version from source, and any other requirements).

Thanks!
