backgroundBecause the server in the production environment does not install the desktop environment, a graphical installation of simple operations is not suitable for batch deployment installations. Therefore, I prefer to install the KVM virtual machine under the command. In combination with some information and personal use, I have outlined some basic and commonly used methods.Installation ConfigurationI.

The KVM virtual machine disk space extension is consistent with the Xen virtual machine disk space expansion approach. The reason is that the XEN/KVM default virtual machine disk format is raw, so the method can be generalized.The raw disk format extension is as follows(1) A

1. Lab description Qcow2 disk format is recommended for KVM virtual machines in centos 7. In this tutorial, centos 6.8 64 virtual machines are installed in KVM.2. Command deployment process 2.1 upload an image Use winscp to upload to/data/ISO/2.2 format a disk 1 virt-install --network bridge=br0,model=virtio --name=v

Use Shell scripts to monitor KVM virtual machines Recently, a friend asked me what software I usually use to manage KVM virtual machines. In fact, I usually use the virsh command to manage virtual machines through the command line. Although redhat has a

First, KVM IntroductionKVM is open source software, the full name of kernel-based virtual machine (kernel-based VM), is an open source system virtualization module, hardware-based complete virtualization, but requires hardware support (such as Intel VT Technology or AMD V technology). Since Linux 2.6.20 is integrated in each major release of Linux. It is managed using Linux's own scheduler, so its core sour

This article was sponsored by Xiuyi linfeng and first launched in the dark world. When we enable or disable a KVM Vm, we usually use commands such as start, shutdown, and reboot. However, sometimes we find that the VM does not respond when the shutdown or reboot command is used to shut down or restart the VM, in this case, we may use destroy for brute force shutdown. Why does this happen? After querying relevant information, we found that these comman

Recently, we have been studying virtualization technology, have a certain understanding of the VMware virtual machine, the latest whim, can you install a virtual machine in a VMware virtual machine?Then the problem comes, first of all, you need a computer, VMware software, (My Computer Configuration slag, memory a bit too much), so we can start, first in VMware t

The KVM virtual machine defaults to the RAW format image format, the best performance, the fastest, its disadvantage is not support some new features, such as support image, zlib disk compression, AES encryption and so on.To use the mirroring feature, the disk format must be qcow2. The following begins the process of a KVM vi
