To create a virtual machine tutorial with Proxmox

Brief Introduction

Proxmox VE (Proxmox virtualenvironment) is an excellent integrated OPENVZ "1" Supporting KVM "2" Application environment. There is an Easy-to-use Web interface, based on the Java UI and kernel interface, you can login to the VM customer convenient operation, as well as Easy-to-use template features, basically with the commercial VPS environment of foreigners almost.

Proxmox to create a virtual machine

1, first login management platform

2, click on the top right corner of the Create VM button, enter the following creation interface

In the General tab, enter or select the intrinsic properties of the virtual machines that you want to create.

3, press "Next" button (same below) switch to the OS tab, enter the following interface:

Select the operating system you want to install, and choose the Linux operating system (2.6 version of the kernel)

4, switch to the CD/DVD tab, choose the installation type

The choice here is to install with an ISO (mirrored file), before you have to prepare a mirrored file for the operating system you want to install. Of course, you can also choose to use the physical CD/DVD driver or do not use any media media "normally, ISO installation".

5, switch to the "Hard disk" tab to set the required storage space or format

If there are no special requirements, usually choose the above settings, you only need to select the disk space you need.

Format selection: QEMU "3", Bus/device:virtio "4"

6, switch to the CPU tab, select the CPU configuration you need

There are no special test requirements, where sockets and cores usually choose 2. And you should try to keep the two parameters as consistent as possible. CPU type, there are many options available (486 to 686 can be selected), depending on the requirements.

7, switch to the "Memory" tab, set the maximum memory you need to use.

8, switch to the Network tab, set some of the following parameters

In general, choose bridged mode (bridging model), model select Virtio (semi-virtualization). Other than the choice of the above is good.

9, go to the "Confirmation" tab, confirm all the hardware configuration parameters

It lists all the configuration parameters for the virtual machine you want to create, and if it doesn't, click the "Finish" button to complete the creation of the virtual machine. If you find a need to modify, click the "Back" button, back to the configuration interface, complete the modification.

The above is the virtual machine in the Proxmox management software creation, you can see that the management interface is really brief and friendly. What else do you not understand, or what you want to discuss, you can contact the Institute of Dr. Jiangjian. These virtual machines can only be created on the server where he is.

Note:

The "1" OpenVZ is an operating system-level virtualization technology based on the Linux kernel and operation system. OPENVZ allows physical servers to run multiple operating systems, known as Virtual Private servers (VPS virtual privateserver) or virtual environments (VE environment).

OpenVZ's host OS and Guestos must be Linux (although different Linux distributions can be used in different virtual environments) than VMware, a virtual machine and Xen, which is a semi virtualization technology. However, OpenVZ claims that there is a performance advantage in doing so. According to the OPENVZ Web site, performance can only be 1-3% loss compared to using a OPENVZ server.

OpenVZ is the foundation of Swsoft,inc, a proprietary software Virtuozzo developed by the company. OpenVZ's authorization is GPLv2.

The OPENVZ consists of two parts, a modified operating system core and user tools.

The "2" KVM (full name is Kernel-basedvirtual Machine) is a fully functional virtualization solution on the Linux x86 hardware platform, including a loadable kernel module Kvm.ko providing and virtualizing core architectures and Processor specification modules.

Using KVM allows multiple hardware including Linux and Windows per virtual machine, including network adapters, disks, and graphics adapter cards.

"3" QEMU is a set of free software for analog processors written by Fabricebellard. It is approximate to BOCHS,PEARPC, but it has some characteristics which are not possessed by the latter, such as high speed and cross-platform characteristics. By Kqemu This open source accelerator, QEMU can simulate the speed of proximity to the real computer.

QEMU supports a number of formats , and the qcow/qcow2 format we choose here is the format it supports. They are able to support copy-on-write format, such as copying when performing a copy operation, only during a write operation. In the reading operation, it is similar to the concept of the reference assignment in java/c# (that is, there is no memory created for the new object at the time of the copy, but rather to allow the new object to execute the same memory address as the old object), and more about the COPY-ON-WRITE principle .

The "4" Virtio is an I/O virtualization framework for Linux , in which the "Example Virtio Driver" section describes the need for QEMU to practice the Virtio virtualized infrastructure in the Linux kernel.
