It's painful to use Dynamic Optimization in SCVMM 2012 R2

I asked a similar question in this forum a while ago. Here is the link.

I read the suggested blogs. However, the pain is persist.

Here is my environment:
1. Two computer with Windows Server 2012 R2 and Hyper-V enabled.
2. One computer with 10GB memory(HV001), another with 4GB(HV002).
3. With different memory on the computers, so I configured the reserves on the host individually. One HV001, the reserve is 5500MB, another is 1000MB. CPU reserve is the same, 10%. As you can see the following screenshot.

I created 3 VMs(2 with 1GB memory each other, the 3rd with 512MB) and put them running on the host HV001.
When I tried to create the 4th VM and put it on HV001, I got the following information.

However, when I tried to run "OPtimize Hosts" and got the same result like the one in my last post.

Is there a easy way to use dynamic optimization in SCVMM?
