This article mainly introduces "the detailed process of installing Ubuntu15.04 and configuring KVM". In daily operation, I believe many people have doubts about the detailed process of installing Ubuntu15.04 and configuring KVM. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "the detailed process of installing Ubuntu15.04 and configuring KVM". Next, please follow the editor to study!

KVM (Kernel Based Virtual Machine) is a free virtualization tool, similar to VMware and Hyper-V, which also allows us to create virtual machines in the host operating system. KVM has been widely used in the open source world, mainly because it can run on all Linux distribution platforms that support hardware virtualization CPU.

KVM differs from Xen and Hyper-V in that it does not require users to use specific system and kernel versions, and only requires a standard Linux kernel to create and manage virtual machines using KVM. KVM supports full virtualization technology, where each virtual machine running on it runs independently without knowing the host system architecture.

Having said that, let's take a look at how to install and configure KVM for Ubuntu 15.04.

Verify that CPU supports hardware virtualization

To run KVM, you must make sure that the CPU where your Linux system is located supports hardware virtualization, otherwise it will not work properly. We can verify it by executing the following command in the terminal:

The code is as follows:

Egrep "svm | vmx" / proc/cpuinfo

If your CPU supports it, you will see a return similar to the following:

If the vmx option is not available, restart the system and enable hardware virtualization in BIOS.

Install KVM for Ubuntu 15.04

Once CPU support is confirmed and hardware virtualization is enabled, we can install KVM and associated dependency packages for Ubuntu 15.04 using the following command:

The code is as follows:

Sudo apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-bin bridge-utils

Enable bridging network

In general, in order to ensure that the virtual machine and Internet communicate with each other, we need to start network bridging in the host. To ensure that the original network configuration is not destroyed, we first back up the network configuration file with the following command:

The code is as follows:

Sudo cp / etc/network/interfaces / etc/network/interfaces-bak

After the backup is complete, we need to make changes to the / etc/network/interfaces configuration file and append the following information to the configuration file:

Please change the above information according to your own network environment, do not copy it!

After the configuration is completed, you need to restart it, and then use the following command to verify whether the network bridge is configured successfully: ifconfig

Start KVM Virtual system Manager

After installing and configuring the bridged network, we can open the KVM virtual system manager using the following command:

The code is as follows:

Sudo virt-manager

Click new virtual machine under the File menu to create a new virtual machine.

KVM has been widely used as a virtualization technology in the industry. It is very simple and easy to use, and it is also very stable. And there is no charge to use KVM, we can manage it through the command line or graphics interface, in the case of hardware equipment support, theoretically scalable unlimited virtual machine.

At this point, the study on "the detailed process of installing Ubuntu15.04 and configuring KVM" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
