Consider about this method. It seems that some guest RAMs are not allocated in qemu_ram_alloc_from_ptr(), that is, host parameter is allocated elsewhere and passed in. I found two: - assigned_dev_register_regions() in hw/device-assignment.c - create_shared_memory_BAR() and ivshmem_read() in hw/ivshmem.c There is no general method to reallocate these memory so far. We may need a flag in struct RAMBlock to track these memory, and ignore them during reallocation. But if there are hwpoisoned pages in these memory, we can not recover. Do you think that is OK?
