There are 2 ways to surf the Internet in a virtual machine or Docker container: Bridging and NAT(1) Basic principle of bridge connectionA virtual machine configured as a bridged network connection mode can be used as a standalone host for the Ethernet of the host, the relationship between the virtual system and the host machine, like two computers connected to the same hub, which can access all the shared r

Docker by default is the Linux with the Network Bridge implementation, in fact, the Openvswitch project as a mature virtual switch implementation, with a richer function. Personally, the future Docker will necessarily support Openvswitch as its default network bridge implementation. Interested students welcome the foll
This article describes how to configure a bridge network under Fedora 19 to allow other machines in the LAN to access virtual machines in KVM. Note: Fedora 19 is the operating system of the host machine.

The priority can be obtained by obtaining the required information (such as the acquisition of a DHCP network) and restricting the virtual machine to surf the net, discarding packets sent out.When the client is prevented from using the extranet:Virsh Nwfilter-define Drop.xmlWhen enabling the client to use the extranet:Virsh Nwfilter-define Accept.xmlWhen you want

Before we talk about the differences between these network devices, we had to understand the conflict domain and Brocast Domain first.Take bus network topology-example, all PCs is connecting to the same bus line. If multiple PCs is sending the signal at the same time, it would create a conflict domain on the bus line. So some signals would be weaken or terminated due to the conflict. Just Like many cars is
