cpu host is to emulate the host processor. Hence, issue the following in terminal – qemu-system-x86_64 -cdrom iso_image -cpu host -enable-kvm -m RAM_size -smp number_of_cores -drive file= disk_image,format= qcow2 So, we will attach an installation media (ISO image) to the Virtual Machine. Next, we need to install an Operating System in the disk image. Install an Operating System in Disk image This would create a file test-img.qcow2 of size 5 GB. f is used for file format (raw, qcow2 etc.)įor instance, qemu-img create -f qcow2 test-img.qcow2 5G qemu-img create -f file_format image_size
With qemu-img, we can manage our disk images offline. Now, we will create a disk image using command-line utility qemu-img. Sudo apt install qemu-kvm Create a disk image for Virtual Machine using qemu-img So, open a terminal and issue the following – sudo apt update Thereafter, we would install the package and related dependencies (if any). Therefore, we would update the Ubuntu repository first to make the latest version of the package available. Since, QEMU package is already available in standard Ubuntu repository. In case you don’t have one, then contact your System Administrator for assistance.
Note: Following operations would require you to have superuser privileges. Then, we would attach a CD-ROM (ISO Image) to the disk image to install an Operating System. In this article, we would discuss how to setup Virtual Machine using QEMU in Ubuntu distribution.įirst, we will install QEMU and create a qcow2 disk image. At the time of writing the article, the latest stable release of QEMU is 4.1.0. Hence, it is capable to run different Operating Systems and Programs on supported architectures. QEMU, released under GPLv2, supports both machine emulation as well as virtualization. Other examples of hosted hypervisors are VMware Player, Oracle VirtualBox & Parallels Desktop for Mac. QEMU (Quick EMUlator) is a type – 2 or hosted hypervisor.
