It turned out that I had a typo all the time in my template, it used
'cpu=' rather than 'cpus='. On this system none of this works:
#pus="node:${node}"
cpus="nodes:${node}"
#pus="nodes:${node},^node:0"
#pus_soft="nodes:${node},^node:0"

Only 'cpus=node:1' or 'cpus=nodes:1' works, cpus=node:2 or node:3 does
not. There is room for domUs:
numa_info              :
node:    memsize    memfree    distances
   0:     30720       1912      10,21,21,21
   1:     28672      22355      21,10,21,21
   2:     24576      24502      21,21,10,21
   3:     32768      31760      21,21,21,10

But, that is a separate issue. The BUG triggers without the cpus= knob.
