Memory initialization

[cips]

Hello All.

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 reboots, like if there was a real powerdown. Sometimes, between restarts of the guest, 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 FF, or something else), in order to emulate a real powerdown-powerup?
Thanks for your help.
C.

Does the memory get "initialized" (zeroed out) when you shutdown/startup instead of a reboot?

Hello.

No, unfortunately it isn't. No matter if I reboot or Powerdown/PowerUp. The memory is not initialized.

Thanks,

Since this is a highly technical question, your best bet would be to ask in the VirtualBox developers list.
