In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the software for free, the software obtains some hardware information (such as the hard disk serial number and BO

KVM Virtual machine Dynamic migration requires no copying of virtual disk files, but requires the same directory structure virtual machine disk files between the virtual hosts that need to be migrated, compared to the need to copy virtual machine virtual disk files in the static migration of a KVM virtual machine. This part of this article is implemented by NFS, and of course it can be implemented by the

In this case, a large amount of data is sent, this results in a higher migration t
