Can you list some examples of dangerous scenarios?
- guest checksums own kernel pages
- clever compiler reuses code for constant pool
- guest patches itself (a la linux alternatives), surprised when it sees
a different instruction
- guest jits own kernel code (like Singularity), gets confused when it
reads back something it didn't write
