Please download the ISO file of the Linux distro you want to install in Qemu VM.įirst, open the Virtual Machine Manager from the system menu: Installing another Linux virtually with Qemu That's it! The installation of Qemu is done. Next, enable and start the libvirt service: sudo systemctl enable rvice & sudo systemctl start rvice To do so, use the following commands one by one: sudo useradd -g $USER libvirt sudo useradd -g $USER libvirt-kvm To make Qemu work, you'd have to add your user to two groups: libvirt-kvm and libvirt. Reboot your system once the installation is over. Once you are all set, you can install Qemu and KVM on Ubuntu using the following command: sudo apt install qemu qemu-kvm virt-manager bridge-utils If you have an intel processor, it should bring the following output:Īnd if you have an AMD processor, it should get you the following output: Virtualization: AMD-VĪlso, make sure your system has multiple cores so that you can allocate some to your VM and still have enough to power the host machine.Īnd if you're not sure, use the following command and the output should be more than zero: egrep -c '(vmx|svm)' /proc/cpuinfo To do so, use the following command: LC_ALL=C lscpu | grep Virtualization Now you can create a new virtual machine and starting it using virt-manager.Before jumping to the installation, let's check whether your machine supports the virtualization or not. When you now try to start the VM, you maybe will get following message: failed to initialize: permission deniedĪs stated out on issue #1095, You solve this by restarting the KVM kernel modules: # sudo rmmod kvm_intel You also should add a GUI for more comfortable configuration: # sudo apt-get install virt-manager Now install the client software: # sudo apt-get install qemu-kvm If the result of this call is 3 or 5, the instruction set is supported. According to, this can be done the following way: # sudo apt-get install msr-tools This is a virtualisation software being contained in the linux kernel and some forum entries on google claim it is as fast as VirtualBox, but on my system it took some configuration before I was able to successfully start a VM on with it.įirst of all, you need to check if your System has the Intel-VT or AMD-V instruction set, because KVM will not be able to run without it.
Because of this I decided to check out KVM. deb package provided on oracles website, but I did not make it. So I tried to make it run by installing the. So I tried to install VirtualBox through the Debian repository but I had to find out, that VirtualBox no longer is contained in the repository. Yesterday I wanted to install a virtual machine with Windows 7 running on it for testing some applications. Since a few months I have Debian 9 (“Stretch”) running on my notebook.
