Let’s add the network bridge definition in this file, :~$ sudo vi /etc/netplan/50-cloud-init.yaml network:Īs you can see we have removed the IP address from interface(ens33) and add the same IP to the bridge ‘ br0‘ and also added interface (ens33) to the bridge br0. In most of the hardware and virtualized environment, netplan file name would be “ 50-cloud-init.yaml” or “ 01-netcfg.yaml”, to configure static IP and bridge, netplan utility will refer this file.Īs of now I have already configured the static IP via this file and content of this file is below: network: In Ubuntu 18.04, network is managed by netplan utility, whenever we freshly installed Ubuntu 18.04 server then netplan file is created under /etc/netplan/. Network bridge is required to access the KVM based virtual machines outside the KVM hypervisor or host. Step:4 Configure Network Bridge for KVM virtual Machines

Now verify the status of libvirtd service using below command, :~$ service libvirtd status Whenever we install qemu & libvirtd packages in Ubuntu 18.04 Server then it will automatically start and enable libvirtd service, In case libvirtd service is not started and enabled then run beneath commands, :~$ sudo service libvirtd start Once the above packages are installed successfully, then your local user (In my case linuxtechi) will be added to the group libvirtd automatically. :~$ sudo apt install qemu qemu-kvm libvirt-bin bridge-utils virt-manager Run the below apt commands to install KVM and its dependencies :~$ sudo apt update

:~$ Step:2 Install KVM and its required packages Run kvm-ok command and verify the output, :~$ sudo kvm-ok Now Install “ kvm-ok” utility using below command, it is used to determine if your server is capable of running hardware accelerated KVM virtual machines :~$ sudo apt install cpu-checker If the output is greater than 0 then it means your system supports Virtualization else reboot your system, then go to BIOS settings and enable VT technology. Step:1 Verify Whether your system support hardware virtualizationĮxecute below egrep command to verify whether your system supports hardware virtualization or not, :~$ egrep -c '(vmx|svm)' /proc/cpuinfo
