(2) Set up: The hypervisor creates and sets up a "context structure" representing a guest

  • Each guest is represented by a 4KB structure
    • Intel: virtual-machine control structure (VMCS)
    • AMD: virtual machine control block (VMCB)
  • It contains fields describing:
    • Guest configurations such as register values
    • Behaviour of HW VT such as what instructions to intercept
    • More details later
