Experiment Three:
win2012r2-test03 virtual machine: Reserved 0%, limit 60%, Weight: 100
win2012r2-test04 virtual machine: Reserved 0%, limit 60%, Weight: 300

Simultaneous stress testing the CPU usage resources of two virtual machines are as follows:

Here we can see win2012r2-test03 CPU usage is about 30%, win2012r2-test04 CPU usage is about 56%.
Conclusion: No CPU resources are reserved, and the higher the weight is, the more CPU is gained when the limit exceeds the total CPU resources.
Experiment Four:
win2012r2-test03 virtual machine: Reserved 0%, limit 70%, Weight: 100
win2012r2-test04 virtual machine: Reserved 0%, limit 60%, Weight: 300
As shown in the following:

Stress tests for both virtual machines as shown in:

Here we can see that although the win2012r2-test03 virtual machine limit is higher than win2012r2-test04, but the weight is lower than the win2012r2-test04, when the higher the weight of the CPU is also the most. Or the same reason as the above test, in the case of Hyper_v total CPU resources, the higher the weight, the more CPU gets.
Experiment Five:
win2012r2-test03 virtual machine: Reserved 40%, limit 100%, Weight: 100
win2012r2-test04 virtual machine: Reserved 0%, limit 100%, Weight: 300
As shown in the following:

Through the above test we can see that although the weight of the win2012r2-test04 is higher than the win2012r2-test03, but because the win2012r2-test03 is set to reserve the CPU, So win2012r2-test03 can use a higher CPU than win2012r2-test04. Through the above reality, we seem to feel that the weight is useless here, really is this? We need to do the next test again, and we'll analyze it again with the following test.
