+config machine "virt-6.2" with qemu-system-aarch64,it report "mem is not supported by this machine type"
+Description of problem:
+When i config the machine with virt-6.2 and config the numa for cpu,it report "mem is not supported by this machine type",but with virt-5.0 it work well,the newer version virt not support it? It is bug or require hardware support?Or compile configure is not correctlly?
+
+when i create vm,get the error report as follow:
+ 
+virsh create test.xml
+```
+qemu unexpectedly closed the monitor: qemu-system-aarch64: -chardev socket,id=charmonitor,fd=34,server,nowait: warning: short-form boolean option 'server' deprecated
+Please use server=on instead

+
+
+I use qmp command "query-machines" get the result as follow:
+```
+{
+      "hotpluggable-cpus": true,

+      "alias": "virt"
+    },
+```
+
+I add the code "mc->numa_mem_supported = true;" in the api "virt_machine_6_1_options",it can supoort numa,but i don't know whether it is affected.
+
+```
