How does virtual box virtual machine software accelerate the network speed in the virtual system?

Problem description ：

The local network speed is very fast , The normal network speed can reach 7Mb/s Even higher , But the network speed in the virtual machine is only a few hundred Kb/s, This will seriously affect the download progress in the virtual machine .

Solution ：

It opens at VirtualBox Virtual machine settings for , Find the network card of the network 1, The default connection method is NAT( Network address translation ), It is amended as follows Bridge network card （Bridge） Pattern , spot OK Save and exit , Restart the virtual machine .
