All ideas welcome.
I'm beginning to think that since this is Archlinux, there is some default
library or new (feature) of the kernel that is killing VirtualBox,
I straced the actual opening of VirtualBox to change from KVM back to
Default, and strace writing to stderr blew up, e.g. over 2M of output, just to
change from KVM to Default, e.g.
strace: Process 32452 attached

I guess a bug is needed.
