still crashing even if kvm paravirtualisation is forced off
will try limited cpu to 75% in each vm

Unfortunately the crash reports show a crash directly inside the host kernel and no VirtualBox code is part of the backtrace. But I don't say that this is not a VirtualBox bug.
Your host has 2 physical cores with 2 hyperthreads per core. If all your VMs run at nearly full speed they put a huge load on your host processor. If you run only two of these VMs in parallel, do these crashes happen as well?
You say that with KVM disabled the setup is more stable but you still experience these host crashes?

it turns out that they still crash with KVM disabled 8 other users are running just 1 vm and their macbooks are not crashing
