Deal with instructions from guest OS that require interaction with the physical hardware. Emulate every single instruction. Dealing with privileged instructions can't run in kernel mode; then we'd be back to our original problem. VMM will deal with handling privileged instructions.

Privileged instructions cause an exception; VMM intercepts these and emulates. How to do the emulate How to deal with instructions that don't trigger an interrupt but that the VMM still needs to intercept.

Guest virtual, guest physical, host physical. VMM locates guest OS's page table. Combines guest OS's table with its own table, constructing a third table mapping guest virtual to host physical. If guest OS modifies its page table, no interrupt thrown. Approach 2 Modern hardware has support for virtualization.

Physical hardware effectively knows about both levels of tables: Hard to do, and goes against our compatibility goal. VMM analyzes code from guest OS and replaces problematic instructions. Some architectures have virtualization support built in.

Hardware support is arguably the best. Makes VMM's job easier. Why so many bugs, though? The Linux kernel is, effectively, one large C program. Careful software engineering, but very little modularity within the kernel itself. Bugs come about because of its complexity. Adversary can exploit these bugs.

Alternative to Monolithic Kernels Put subsystems—file servers, device drivers, etc. There will still be bugs but: Fewer, because of decreased complexity. A single bug is less likely to crash the entire system. Why isn't Linux a microkernel, then?

High communication cost between modules. Not clear that moving programs to userspace is worth it. Hard to balance dependencies e. Spend a year of developer time rewriting the kernel or adding new features? Microkernels can make it more difficult to change interfaces.

Some parts of Linux do have microkernel design aspects.Sep 21,  · This video explains what is required for the Week 4 assignment in MIS Week4 BA Assignment Application Problem 4 W4 Assignment “Application Problems 4” Application Problems Week 4.
