Hmm - I thought I had checked that in comment #9 where I used a bigger canonistack env.
But locally in KVM guests I can show that
1 vpu - our fail
2 vcpu - working
And since we are dealing with software meant at parallelization it might be that this just needs at least 2 cpus to run properly.
That also explains why all the container based tests worked as they see more CPUs.
