![]() This patch extends the functionality of the max-ram-below-4g option to also allow increasing lowmem. Use case: Give as much memory as possible to legacy non-PAE guests. While being at it also rework the lowmem calculation logic and add a longish comment describing how it works and what the compatibility constrains are. Note: This is a incompatible change. When setting max-ram-below-4g to a value larger than 3.5G (or 3G with gigabyte alignment) it has no effect on older qemu versions: qemu silently ignores it. With the patch applied it actually has an effect and changes the ram layout. Highly unlikely to hit in practive though as there is no reason start old qemu versions that way.
