Can you provide a simple reproduction scenario? What does one have to do to see this?

A VM reset should clear memory. A caveat is that a given guest OS may not perform a full reset but only a soft reboot, which does not clear memory.

Hello all.

I was suggested to post my question here.

Here my doubt:

I noticed this behavior, which is probably expected: dumping the RAM of a guest (with ".pgmphystofile" command) I saw that the memory is not initialized between virtual powercycle, like if there was a real powerdown. Sometimes, between restarts of the guest (with a shutdown and then a restart), I find some memory artifacts belonging to processes that shouldn't be there. I assume this happens because I'm not restarting the host system, so probably the RAM is just remapped, but not initialized. This is a bit annoying in some case, especially if you are using the system for testing purposes.

Is there a way to force the guest to initialize the allocated RAM to zero (or something else), in order to emulate a real powerdown-powerup?
Thanks for your help.
