Abstract: two methods are available for KVM Virtual Machine network configuration: Nat and bridge. NAT configuration principles and procedures. Nat is applicable to desktop host virtualization.Problem After the client is installed, you need to set up a network interface for it to communicate with the host network and the client network. In fact, to use network c
1. Conclusion The differential generation of virtual machines using backup images can quickly generate a large number of virtual machines and save disk space, which is of great significance in the production environment. After testing, the read Pressure on the backup image is very small, and the system pressure is main
