Core uses LXC (Linux namespace Container) technology and bridge technology to achieve virtual host and virtual network simulation. LXC uses the Process Group resource Management framework in the Cgroups subsystem to implement a virtual host as a relatively independent process for the same group. LXC has been added to t

Architects have creative designs that can sometimes save a lot of hardware costs and later maintenance costs. In some cases, the use of good Pvlan can simplify network management, but also meet the needs of security isolation. Concept The concept of Pvlan has long been in the physical network, vsphere distributed switch implemented this concept in the hyperviosor layer.

In the process of using dual-computer software, if the system is Red Hat 5.x default system installed after the Xen kernel, then the Xen kernel boot will have virtual network card (VETHX, vif0.x, virbr0, XENBR1, etc.) exist. This will directly lead to dual-computer software in both machines will have the same IP addre
