+when use `<currentMemory>` less than `<memory>` - at/after shutdown of guest os cpu hangs on 100% and lasts long- approximately 3-5 minutes
+if change to
+```

+  <currentMemory unit='KiB'>33554432</currentMemory>

+
+problem occurs not (shutdown of VM takes some seconds) in cases when not used balloon device:
+1 `<currentMemory>` equal to `<memory>`
+2 memballoon driver disabled in windows
+3 memballoon disabled on libvirt with "model=none" (and therefore not passed to qemu command line)"""

+ * used drivers from virtio-win-0.1.262.iso - membaloon ver 100.95.104.26200 
+ * possible combination of all or some components 
+
+monitored next: 
+`virsh dommemstat VMName` at shutdown time there grows "rss" till MaxMem, but very slowly.
+aLso on `virsh setmem VMName --live --size 32G` 
+rss grows slow - but takes 2 times less than at simple shutdown time ( = at shutdown seems occurs memory allocation and deallocation at the same time)
+
+so something with some or all libvirt/qemu/balloon parts not so nice"""
