-Guest os=Windows , qemu. Shutdown very slow. Memory allocation issue.
-Description of problem:
-simplifiying - libvirt config:
-```
-<memory unit='KiB'>33554432</memory>
- <currentMemory unit='KiB'>131072</currentMemory>
-```
-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
-```
-<memory unit='KiB'>33554432</memory>
- <currentMemory unit='KiB'>33554432</currentMemory>
-```
-then shutdown takes less some seconds
-
-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)
-Additional information:
-on the guest :
- * 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
