In order to better simulate the production server, relevant tests can be carried out in the local virtual machine. Generally, the actual production server can only be the same as the local host or intranet, so it is very important to set fixed IP for virtual machine and select host only mode for testing ...

Because you want to write a simple operating system, you need to install a virtual machine to simulate the hardware. VMware is not suitable for this scenario, because you will use hardware level virtualization, and bochs, the open-source virtual machine, uses software to virtualize all the hardware, so debugging can be very fine-grained. For ex ...

After the upgrade of red hat system (CentOS7/RHEL7), the naming method of "consistent network device interface" is adopted for network card naming, resulting in different network card names of different devices. In order to ...

After VMware sets the disk size of the virtual machine, it finds that the disk space is insufficient. How to expand the disk size at this time? First of all, when the virtual machine is shut down, right-click the settings, select the hard disk, and expand, so that the size of the disk can be increased. But without setting partition and disk mo ...
