Well, that was a noop. But xl.cfg states "nodes:0-3,^node:2", so this
should work:
cpus="nodes:3,^node:0"
cpus_soft="nodes:3,^node:0"

xl create -f fv_sles12sp1.f.tst.cfg
libxl: error: libxl_sched.c:62:libxl__set_vcpuaffinity: Domain 16:Setting vcpu affinity: Invalid argument

libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 16:Destruction of domain failed

Same for nodes:2..., just nodes:1... works.

And after some attempts, cpus="nodes:2/3" fails too.
There is no indication what is invalid.
