Resizing Memory With Balloons and Hotplug
In a virtualized environment it is often necessary to resize the amount of memory allocated to a particular copy of Linux. There are currently two viable approaches to adding and removing memory: memory hotplug and a balloon driver. We will compare and contrast how these resizing technologies work independently, weighing the benefits and drawbacks of each one. We also will show how these two resizing technologies could be used together to provide the best of both worlds.
