Apparently, when i got one and another one is in waiting the CPU crunches one of the pythons ones and nothing else.

Same here. I have a 12 cores AMD Ryzen and even if i stop all other wus, the system crunchs only 1 python.

When i have one of these python jobs i can force rosetta to crunch classical WU's by cancelling all the pythons in the queue. Anyway it doesn't finish them all. I get a unmanageable VM message after several hours of my electricity wasted so i killed the tasks.

Edit: the funny thing is i don't get -of course- those python VM jobs on another machine which has no virtualbox installed. So a radical solution to this problem could be to uninstall virtualbox. I won't.I use it.
