The somites arise directly from which of the following?

Full Virtualization The context for this question is the same as the previous question. An engineering firm is running a critical, unmodified legacy CAD application inside a fully virtualized VM on an older x86 server. The application frequently makes privileged calls that interact directly with the hardware. An administrator notices poor performance and learns that this specific, older x86 architecture has a “quirk” where certain privileged instructions, when executed by the guest OS (which is running in an unprivileged mode), fail silently instead of causing a trap to the hypervisor.  [2 points] What technique does VMware ESX use to overcome this architectural limitation and ensure the guest OS functions correctly? 

Lock/Barriers The context for this question is the same as the previous question.   [1 point] What is the minimum number of additional processors that would warrant a Round 3?

Potpourri Answer the following questions with respect to the MCS barrier algorithm:   [2 points] (Answer True/False with justification) (No credit without justification)  For the correct functioning of the algorithm, it requires an atomic read-modify-write instruction to be supported in the architecture.
