    This is really a CPU architecture/instruction mechanics question — See on why certain instructions aren’t “virtualizable” (unless you’re going to emulate the
    Definition; Difference between sensitive instruction and privilege instruction; Virtualizable and Non-virtualizable. How to “trap-and-emulate”? Introduction toSensitive instructions: only executed in kernel mode. 0 Privileged instructions: trap when run in user mode. 0 CPU architecture is virtualizable only if sensitive.
    x86 is not virtualizable. 0 Some instructions (sensitive) read or update the state of virtual machine and don’t trap (non- privileged). 0 17 sensitive
