What happened?

Upgrade VBox 7.2.2 -> 7.2.4
installed guest additions 7.2.4 in all guest VMs.

Running 3 guests, all Ubuntu 24.04, with 2 CPUs configured for each guest. Host computer has 8 CPUs.

I see guests using > 100% CPU each in host's top display, although the guest VMs are idle with no work.

How can we reproduce this?
