How to start the KVM virtual machine using virt-manager.

First start the graphical interface with the command virt-manager

# virt-manager

Click the icon above to create a virtual machine

Name the virtual machine kvm1, and choose where to start the virtual machine. If you are installing a new OS, you can select the first option. If you already have an installed image file, select the last one (as shown above)

Next you need to tell virt-manager the location of the image.

Click "Browser"

I have a cirros-0.3.3-x86_64-disk.img image file in my system. Cirros is a very small linux image, which is very suitable for testing. You can download it from http://download.cirros-cloud.net/ and put it in the / var/lib/libvirt/images/ directory. This is where KVM looks for image files by default.

Allocate CPU and memory to virtual machines

Click "Forward", and then confirm the information, you can start the virtual machine.

Virt-manager will open the console window of the virtual machine kvm1, and you can see the startup situation.

Virt-manager can manage all kinds of virtual machines. The interface is intuitive and friendly, and it is easy to use. At the same time, we can also use the command virsh to manage virtual machines, such as checking virtual machines on host computers.
