[RFC] virtio-mem: paravirtualized memory
...omething
similar would be needed for vhost. Re-sizing of memory slots has to be
an atomic operation. [medium]
- NUMA: Most probably the NUMA node should not be part of the virtio-mem
device, this should rather be indicated via e.g. ACPI. [medium]
- x86: Add the complete possible memory to the a820 map as reserved.
[medium]
- x86/powerpc/...: Indicate to which NUMA node the memory belongs using
ACPI. [medium]
- x86/powerpc/...: Share address space with ordinary DIMMS/NVDIMMs, for
now this is blocked for simplicity. [medium/hard]
- If the bitmaps become too big, migrate them like memory....
