Lastly, why is qemu 4.5M but kvm-qemu-img is only 125K?
I would assume it's just the module that works on image files. AFAIK, you don't need qemu if you have KVM. The same way you don't need KVM if you use Xen ...
This is not the sense I gather from the various kvm websites. For example, http://www.linux-kvm.org/page/Main_Page states this:
"KVM also requires a modified QEMU although work is underway to get the required changes upstream."
Now, I am not sure what this means as I lack any context. Does it mean that one needs a specialized qemu now and expresses hope that the standard qemu will incorporate the necessary changes sometime later? Or does it mean that qemu is needed now but that no qemu will be needed when "upstream" incorporates the recommended changes? As the date of this text is not later than 2008 July 21 is it out of date? Have the necessary changes been incorporated by upstream by now?
Since upstream is not defined it may mean the qemu project or it might refer to the Linux kernel team. I suspect that the former is the case and that qemu will be required to support kvm in the foreseeable future, if not forever.
