[Qemu-devel] How to persist guest ram in qemu to a file?

[Joel Fernandes]

Hi Tianyou,
I see that you were trying to persist RAM in Qemu to a file.

Could you share this work with me? I looked for it but couldn’t find it.

I tried -mem-path=<file> but the file contents are always all 0’s. I tried 
hacking qemu to mmap the file as MAP_SHARED but no luck.

Here’s my Qemu command line:

Thanks in advance for the help,
