charset="utf-8" Default RAM backend depends on numa_uses_legacy_mem(), which is infulenced by -numa options on CLI or set-numa-node QMP command at preconfig time. If QEMU is started with '-preconfig' without -numa, it will lead to creating default RAM backend even if later set-numa-node is used to assing RAM to NUMA nodes using 'memdev' NUMA option. That at best will waste RAM object created by default and with next patch adding a check to prevent usage of conflicting '-M memory-backend' and '-numa memdev' options, it will make QEMU error out if user tries to configure NUMA at preconfig time with memdev option, making set-numa-node unusable. To fix issue, move preconfig loop before default RAM backend is created, so that numa_uses_legacy_mem() would take into account effects of set-numa-node commands executed at preconfig time.
