+BUG: Segmentation fault when -object memory-backend-file use readonly=on, prealloc=on together
+Description of problem:
+Segmentation Fault while booting VM.
+Steps to reproduce:
+1. set qemu boot params to `-object memory-backend-file,id=mem1,readonly=on,prealloc=on,mem-path=<any-img-file>,size=4G`
+2.
+3.
+Additional information:
+It might not be a bug, probably a feature.
+The reason of this segfault is:
+readonly would mmap the backend file using PROT_READ, make it readonly,
+but the prealloc=on would touch_pages the memory mmaped by the file.
+SO the segfault happens.
+
+But there is no docs about this segfault condition (the readonly and prealloc cannot be used together.)
+
+And maybe there is a way to solve this problem, I think.
+Use mmap the memory backend file to PROT_READ|PROT_WRITE at the beginnning, after touch_pages, then mprotect the memory.
+change the prot to readonly if required.
