I have seen this before, this issue is on my list. The problem is only
occurring on Dom0 repinning. After having done the actual
xc.vcpu_setaffinity call in XendDomain.py:1426, xend wants to set an
entry in the Python array: cpus[v] = cpumap. This array has not been
properly allocated for Dom0, thus forcing an assignment to an empty
list. This is more or less cosmetic as long as you only pin one VCPU,
but pinning all (e.g. xm vcpu-pin 0 all 4-7) will stop after the first
VCPU, so you have to use some kind of shell-for-loop workaround _and_
ignore the error message. I haven't found a proper way to fix this yet.

Andre.
