You've found a real bug. Virt-top is not very well tested against qemu, or rather that should be not tested at all. But I'll go and try to make it work with qemu now. Probably take a few hours though ...
The patch to fix that particular bug is attached. There may be other though, still testing ...
OK, I'm fairly sure this is the only patch needed.
I'm going to roll this in to the next (0.3.2.8) release later.
Libvirt needs works to support block and network stats from QEMU/KVM. Virt-top won't fail because this is missing, it just can't display anything in those columns. The work as far as I understand it is fairly simple, but also lower down on my list of priorities at the moment.

Another thing which virt-top uses but which is missing in QEMU/KVM is physical CPU usage and CPU pinning. I have absolutely no idea if qemu supports this -- I assume it does through ordinary Linux mechanisms such as numactl. As for KVM, no idea whatsoever.
maybe you can ask kvm people:-)
anyway if the new version will be uploaded i can try it again.

qemu and kvm are idential in this respect. The only difference is in smp, where qemu maps all vcpus to a single host thread and kvm has a host thread for each vcpu thread. sched_setaffinity() and similar work as expected.
