Three virtual machines are installed on a 2G memory desktop and run well, that is, swap is used more often. See the previous article. Now the platform is basically ready, with its own laptop as the general control, and four machines running on the lab desktop (one solid and three virtual machines), coupled with one server, can do a lot of things, because KVM is a bridge network, the three virtual networks are consistent with the real-world status. They all contain their own IPv4 and IPv6 addresses in the campus network. An IPv4 address is a 10-segment Intranet address. The Internet access requires student ID authentication, and a maximum of two terminals can be online. However, IPv6 resources are very powerful, and each machine is assigned a public IP address. For example:
Therefore, each machine can be used directly in an IPv6 network without authentication. Therefore, ipb6 is used. The first step is to configure the IPv6 network source. For more information, see:

The DNS of beiyou is easy to use, but the source of beijiao is indeed ping6, And then you can see another article.
