+ *
+ *
+ * The isolation states (hv_partition_isolation_state) are sub-states of
+ * ObPartitionActive that apply to VBS and hardware isolated partitions.
+ * For VBS isolation, the trusted host VTL 1 component uses the isolation
+ * state to establish a binding between a hypervisor partition and its
+ * own partition context, and to enforce certain invariants.
+ *
+ * Hardware-isolated partitions (including partitions that simulate
+ * hardware isolation) also use isolation states to track the progression
+ * of the partition security state through the architectural state machine.
+ * Insecure states indicate that there is no architectural state
+ * associated with the partition, and Secure indicates that the partition
+ * has secure architectural state.
+ *
+ * ObPartitionRestoring is treated differently for isolated partitions.
+ * Only the trusted host component is allowed to restore partition state,
+ * and ObPartitionRestoring can only transition directly to/from secure.
