offline from the network to help ease security concerns. This is a good method for virtualized environments.
If the virtual machine can be detached from the environment of the Management Program, intruders will have the opportunity to access the management program that controls the virtual machine, thus avoiding the security control system specially designed to protect the virtual machine. Security issues in the virtual world are trying to get out of the control of virtual machines. Although no

Article Title: Server clinic: Make the virtual file system work. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
A Virtual File System (VFS) is an abstract concept with extremely efficient usage. Several popular languages now support VFS constructor. Cameron Laird shows
The basic idea is how to make the CPU hyper-threading or multi-core more balanced and efficient use. We know that there is always a CPU dedicated to responding to the NIC interrupt requests. If the network request package is very large, A single CPU may not be able to handle the problem. Therefore, you need to activate multi-core or hyper-threading to distribute Nic interrupt requests to multiple CPUs for execution, so as to improve the overall
Server How to shrink the MSSQL log file is a recurring problem, but this problem in the elite area has a lot of answers, I do not repeat here.
Now let's talk about the root cause, which is how to make the log files no longer grow.
