Server Side Disable SeLinux Edit the configuration file: vi /etc/selinux/config Modify as follows: #SELINUX=enforcing # Comment out #SELINUXTYPE=targeted # Comment out SELINUX=disabled # Add this line Then reboot the system: reboot # Restart the system Create a Directory Using the root user, create a directory named /nfs. Note: It’s best to check which partition has the most space by running df, as the root (/) partition may not have the most space. In some automatic partitioning setups, the /home partition may have the most space. ...

What Is Bridging Bridging highly simulates a network card, making the router believe that the virtual machine’s network card truly exists. Personally, I feel it’s similar to resistors connected in parallel, whereas NAT (another common virtual machine network connection method) is more like parasitizing on the host’s network card. Why Use Bridging It allows you to treat the virtual machine as a completely independent machine, enabling mutual access with the external network (which is not possible with NAT). ...

Installation Process Installed Version: CentOS 6.3 Using Win32DiskImager to create a USB flash drive image was unsuccessful; installing from an external USB optical drive was successful. During the installation process, make sure to select the “Virtual Host” installation mode. The rest can be set to default or slightly modified, such as choosing the time zone. After installation, it will include the KVM suite and SSH. Installation Notes No internet connection is needed throughout the process, which is much better than Debian and Ubuntu. You’re not forced to set up a non-root user. Before installation, be sure to check whether your CPU supports virtualization and enable the motherboard’s virtualization setting. If the motherboard supports virtualization but doesn’t have a virtualization option, you can still use virtualization as it’s definitely enabled by default. There’s a saying that Intel CPUs with a ‘K’ cannot perform virtualization. ‘K’ means Intel CPUs that can be overclocked. It seems that faster and newer CPUs are not necessarily better.
