173This ioctl allows the user to create or modify a guest physical memory
174slot. When changing an existing slot, it may be moved in the guest
175physical memory space, or its flags may be modified. It may not be
176resized. Slots may not overlap.
177
178The flags field supports just one flag, KVM_MEM_LOG_DIRTY_PAGES, which
179instructs kvm to keep track of writes to memory within the slot. See
180the KVM_GET_DIRTY_LOG ioctl.
181
182It is recommended to use the KVM_SET_USER_MEMORY_REGION ioctl instead
183of this API, if available. This newer API allows placing guest memory
184at specified locations in the host address space, yielding better
185control and easy access.
