The total number of virtual machine cores cannot exceed the number of host cores. If it exceeds, it will warn and remind, it is not recommended to configure too high otherwise the host will get stuck

8 Network Type-Bridge

8 Network type-explain non-operation steps (very important)

Bridge mode: directly connect to the real network card of the host and then communicate (minimal restriction)
NAT mode: use virtual network card VMnet8 for communication
Only host mode: use virtual network card VMnet1 for communication

注意：	桥接自默认动选择一个真实网卡（可能是无线也可能是有线）。
		如果使用无线上网，自动桥接到有线网卡了就会出现无法访问网络。
		所以要手动指定桥接到的真实网卡

Here I was found to be unable to connect to the Internet after the installation was completed because of the automatic bridging here.

8 Manually set the real network card of the bridge
