[vbox-dev] reducing state-file size (and the time to create it)

[Petar Bogdanovic]

Hi,

VirtualBox seems to be very efficient when saving the contents of a VM's
memory.  If your VM just booted, saving its state will take less than a
second, while saving a VM that, for example, has been fetching many
things over NFS (and therefore has full caches claimed by the OS) will
take its time because almost all $memsize has to be written down.

How does VB know what parts of memory have to be saved and is there a
way to influence this by some trivial action inside of the VM?

Thanks,
