I am sorry for being dense here but why cannot you mark that memory hotplugable? I assume you are under the control to set attributes of the memory to the guest.When I said two OS's I meant multi-kernel environment sharing the same hardware and not VMs. So we do not have the control to mark the memory hotpluggable as done by BIOS through SRAT.
If you are going as far as to pass in custom kernel command-line arguments, there's a bunch of other fun stuff you can do. ACPI table overrides come to mind.
This facility can be used by platform/BIOS vendors to provide a Linux compatible environment without modifying the underlying platform firmware.
