I got some issues when running my Windows VM on Ubuntu 16.04 LTS, it seems that the VM is taking all the memory and CPUs and the system was slowed down really bad.

My Current System is,
Ubuntu 16.04 LTS Memory: 15.6 GiB Processor i7-5600U @ 2.6GHz x 4
My VM system is,
Windows 8.1 Pro Installed Memory: 8.00 GB System type : 64-bit
When running the VM, my system performance looks like the following graph,

And the configuration of my VM is, enter image description here

My machine runs really slow and the fan is much noisy than normal. By the way, my Windows is idling without running any program.

Does anyone have the similar issue?

Thank you in advance.

From the comments...

In the guest OS settings, by setting CPU=4 you've committed all of the CPU resources in your computer to the guest VM. Host operation will slow to a crawl. Generally speaking, you shouldn't commit more than half of the number of physical CPUs to a guest VM.

In the guest OS System settings, set the memory to 2048 and the CPU's = 2.
