I was trying the steps from Lena (comment #1) and Marius (comment #2).
But I'm not seeing it. Neither in a container (with kvm allowed for the guest) nor in a nested VM.
After being puzzled for a few seconds I realized that a lib would only ever read /sys/devices/system/cpu/possible on a multi-cpu system and my VM was single CPU.
Changing it to 3 vcpus made it trigger.
And I can see it every time I try to start the guest.
