Hi,

Now qemu ram live snapshot feat= ure has some problems, it is based on ‘ram live migration’.

The time of snapshot depends on= completion time of migration, which is not measurable. Also It may canR= 17;t achieve migrate in some situation.

I have seen discussion about that in your previous emails, and there seems to be a fe= asible scheme.

I wa= nt to know if there is any new progress or somebody is trying to realize th= e program.

Best Regards<= /p>

Hailiang Zhang
