guest-visible paging state
- This is the state that the guest thinks the machine is using
- It consists of
- - guest physical memory
- The physical memory addresses the guest is allowed to use
- (see shadow page maps, below)
- - guest page tables
- (we care about when the current one changes)
- - guest paging registers (these are never written to hardware)
- CR0
- CR3

shadow paging state
- This the state that the machine will actually use when the guest
- is running. It consists of:
- - current shadow page table
- This is the page table actually useed when the guest is running.
- It is changed/regenerated when the guest page table changes
- It mostly reflects the guest page table, except that it restricts
- physical addresses to those the VMM allocates to the guest.
- - shadow page maps
- This is a mapping from guest physical memory addresses to
- the current location of the guest physical memory content.
- It maps from regions of physical memory addresses to regions
- located in physical memory or elsewhere.
- (8192,16384) -> MEM(8912,...)
- (0,8191) -> DISK(65536,..)
- - guest paging registers (these are written to guest state)

host paging state
- This is the state we expect to be operative when the VMM is running.
- Typically, this is set up by the host os into which we have embedded
- the VMM, but we include the description here for clarity.
- - current page table
- This is the page table we use when we are executing in
- the VMM (or the host os)
- - paging regisers
