Hi I sent this to qemu-discuss with no success so resending to qemu-devel.
I am doing some very low level OS design work and wanted to be able to alter some values in the physical memory of my QEMU guest. I can see quite a few ways to print/dump both physical and virtual addresses but nothing that can alter arbitrary physical/virtual addresses? Does such a feature exist in Qemu and if it does are there pointers to documentation for it? I do see that we can use file backing for very large memory regions via the memory-backing-file option but I am not really trying to alter massive regions of memory in this case. Cheers Stephen Bates
