Dynamic memory management

This is getting me excited:
http://www.linux-kvm.org/page/FAQ#Is_dynamic_memory_management_for_guests_supported.3F

Looks like a big RAM use reduction is possible. Looks like Whonix-Gateways’s might take very little RAM on its own because it uses the same memory as Whonix-Workstation. Whonix-Gateway GUI wastes RAM would no longer be an argument.

Can you work on this please? I guess we’ll add this after Whonix 9, because this needs quite some stability testing.

I just love Linux :smiley: Sure I’ll test it out. More info on how to use posted in /dev

True and the resource savings are potentially huge.

Any update?

All implementations of hypervisor memory deduplication leak information about processes across VMs. I documented how to enable it but warned about the implications and opted against having it on by default.

Is this https://www.whonix.org/wiki/KVM#Enabling_HugePages ?

No. Hugepages is a different feature and has worse problems.
