Right now, there is some inconsistency between hotplugged and
coldplugged memory. DIMMs added via "-device" result in different stats
than DIMMs added using "device_add".
E.g.
[...]
-numa node,nodeid=0,cpus=0-1 -numa node,nodeid=1,cpus=2-3 \
-m 4G,maxmem=20G,slots=2 \
-object memory-backend-ram,id=mem0,size=8G \
-device pc-dimm,id=dimm0,memdev=mem0 \
-object memory-backend-ram,id=mem1,size=8G \
-device nvdimm,id=dimm1,memdev=mem1,node=1
Results in NUMA info
(qemu) info numa
info numa
2 nodes
node 0 cpus: 0 1
node 0 size: 10240 MB
node 0 plugged: 0 MB
node 1 cpus: 2 3
node 1 size: 10240 MB
node 1 plugged: 0 MB
But in memory size summary:
(qemu) info memory_size_summary
info memory_size_summary
base memory:
4294967296
plugged memory:
17179869184
Make this consistent by reporting all hot and coldplugged
memory a.k.a. DIMM and NVDIMM as "plugged".
