I don't think anyone has hit the 16 CPU limit - nor would anyone be
likely to hit it...
Keep in mind that the number here is ONLY for the number of VCPUs that
Dom0 has. The hardware may have 64 CPU cores - but only 1-2 allocated
for Dom0. I really doubt any sane configuration would have more than 16
VCPUs set for Dom0.
