Unfortunately, yes, unless you have also applied Jeff's pending patches
for qemu that actually enable optional 'top':

You're very bleeding edge; I won't push my patches to libvirt.git until
qemu.git also has matching patches, so in the meantime, you have to
carry patches on both repos.  Peter has been doing some rpm builds of
the bits and pieces for integration testing, but I'm not sure if he is
planning on publishing them for public consumption yet.
