KVM Series notes (1)

Hello everyone, from today to write a KVM related notes, on the one hand is to summarize, and second as a lecturer, I also hope to write some notes for your reference, limited capacity, a lot of advice.

KVM series of notes Ignore most of the principle of knowledge, directly from the experimental aspects, if you want to know more about KVM or virtualization-related theoretical knowledge, you can refer to the Red Hat official website or other forum experts in the explanation, here is not more time, I all the text and all in their own notebook made out, Just write out the principle, so may update will be a bit slow, forgive me, if there is a problem, can leave a message or Q I (83193100).

No more nonsense, KVM Series notes (1) Start with the installation, the lab environment is VMWORKSTATION11, the Redhat version of the OS is installed, and remember that because we are building VMS inside the VM, VMS must turn on virtualization support

After entering the newly installed Redhat system (the process of installing the system is not much written), open the command line terminal to see if the CPU supports the virtualization grep "VMX"/proc/cpuinfo if this tag is representative of the virtualization function, otherwise it will not play.

Before installing KVM, we first make a bridge network card, this bridge network card is used for the GUESTVM machine can communicate with the physical machine host directly, about the KVM network mode we have to write a separate article in detail under the understanding.

By restarting the network card service, ifconfig see that Br0 has an IP on it ok.

Installing the KVM-related components below starts with the need for a Yum source, which is easy to install with Yum.
