Virtual Machine Manager is one of the best hypervisors available for the Linux desktop. This is well-designed and well-functioning QEMU/KVM virtualization software that takes Linux desktop virtualization to the next level.
For installing Virtual Machine Manager
To install Virtual Machine Manager, type the following command into the terminal.
# For Debian/Ubuntusudo apt install virt-manager # For Fedora/RHEL/CentOSsudo install dnf virt-manager
From there you can open the Applications menu and search or browse through the Virtual Machine Manager.
You can also use the following command to open the application. Going here Linux Server Support.
Creating virtual machines
The application opens and you are greeted by a screen that looks like the following image.
Next, you want to access the .iso file or the files you want to use to create your virtual machines. You can use any Linux distribution, Windows virtual machines, or you can follow the online tutorial to run a MacOS virtual machine.
Remember where you save the .iso files. I have a folder called ISO files in the Documents folder, but you can do whatever you want. In this tutorial you will learn how to create a CentOS 8 virtual machine.
First click on the icon in the upper right corner. This is an icon for creating a new VM.
You will receive a message confirming where you want to start the installation of the VM. Leave it on the local installation media (ISO image or CDROM) and click Next.
On the next screen, tap the Browse button…. This takes you to a screen that has only one default path in /var/libvirt/images. You can add another one by clicking on the extra in the lower left corner.
Press +. Name the folder as you like. This is your ISO file folder, so name it to remember. Tap Browse again. This brings you to a screen where you can navigate to your ISO folder and select it as backup path. Go to where you save your .iso files and click Open in the upper right corner. Then click Done.
Your new backup path should now appear in the page window. Click it, select the .iso file you want to use, and then click the Select volume button. If you do not have a .iso file from a lesser-known distribution, the Virtual Machine Manager automatically selects the operating system you have. In the case of this manual this is the case. Click on Forward.
You can now configure the virtual memory and processors. The virtual machine manager sets the default value according to the operating system found in the previous window. You can change this value as you wish, but keep in mind that it may not work properly if you go below the default value. Select the memory capacity and press Next.
On the next screen, select the storage path. You can save the default value, which is in /var/lib/libvirt/images, or you can create a different path by following the same steps as described above. You can also disable the memory of virtual machines, which can be useful when using a system like Kali Linux or TAILS. In general, they do not need to be stored, so there is no need to create and use storage space. Set the storage capacity and press the Forward button.
You can now specify a name for your virtual machine and change any other configuration by checking the Configuration for installation checkbox. If you want to add additional storage or network devices or change the way you access the virtual machine remotely, check the corresponding checkbox. You can also change these settings later, but it is more convenient to do this before installation.
You can also specify information about the network connection. You can leave it as the default in NAT or change it to something else. Hint: Even when using NAT, you can connect to these virtual machines over the network using the virbr0 network adapter created when installing the Virtual Machine Manager. You can operate virtual servers without a headset and remotely connect them to SSH or other resources within this IP address range.
Click Finish to start the installation.
If you are prompted and the virtual network is not active, press Yes to start the network.
Hint: If you need to run the virtual machine in the future, you must first start up the virtual network. You can do it with a team:
Standard sudo virsh net-start
You will see a screen that shows your connection to the virtual machine and other settings. You can configure the virtual hardware, take snapshots of the virtual machine, send stop and restart signals and keyboard shortcuts such as Ctrl + Alt + Delete and Ctrl + Alt + F2 to switch to TTY mode on the guest line.
They’re functional now. I have run many guest operating systems in Virtual Machine Manager with great success, so I recommend you look at some of the best Linux distributions with your new hypervisor. There are also more advanced features of Virtual Machine Manager that we will discuss in a future article.
That’s what it looks like:
