QEMU (Quick EMUlator) is a type – 2 or hosted hypervisor. Other examples of hosted hypervisors are VMware Player, Oracle VirtualBox & Parallels Desktop for Mac. QEMU, released under GPLv2, supports both machine emulation as well as virtualization. Hence, it is capable to run different Operating Systems and Programs on supported architectures. It is written by Fabrice Bellard. At the time of writing the article, the latest stable release of QEMU is 4.1.0. In this article, we would discuss how to setup Virtual Machine using QEMU in Ubuntu distribution.
First, we will install QEMU and create a qcow2 disk image. Then, we would attach a CD-ROM (ISO Image) to the disk image to install an Operating System.
QEMU is a generic and open source machine emulator and virtualizer.
Multipass presents Mac users with a simpler alternative to software like VirtualBox and QEMU. It lets you initialize an Ubuntu VM in seconds, allowing you to quickly test code, and then delete the instance with a simple command. On macOS, the program uses hyperkit as a backend by default, but if you prefer, you can use VirtualBox for. How to Install QEMU on Ubuntu. QEMU is a Linux emulator used to create virtual machines. Many people use Virtual Box on Windows, but fir Linux, you can use QEMU instead. Check if the CPU has the support of hardware for virtualization. Thom Holwerda 2020-11-11 Mac OS X 9 Comments I booted the arm64e kernel of macOS 11.0.1 beta 1 kernel in QEMU up to launchd. It’s completely useless, but may be interesting if you’re wondering how an Apple Silicon Mac will boot.
Note: Following operations would require you to have superuser privileges. In case you don’t have one, then contact your System Administrator for assistance.
Install QEMU in Ubuntu
Since, QEMU package is already available in standard Ubuntu repository. Therefore, we would update the Ubuntu repository first to make the latest version of the package available. Thereafter, we would install the package and related dependencies (if any). So, open a terminal and issue the following –
Create a disk image for Virtual Machine using qemu-img
Now, we will create a disk image using command-line utility qemu-img. With qemu-img, we can manage our disk images offline.
Qemu Gui Mac
where,
-f is used for file format (raw, qcow2 etc.)
For instance,
This would create a file test-img.qcow2 of size 5 GB.
Install an Operating System in Disk image
Next, we need to install an Operating System in the disk image. So, we will attach an installation media (ISO image) to the Virtual Machine. Hence, issue the following in terminal –
where,
-cdrom is for iso_image,
-cpu host is to emulate the host processor. There is a list of supported architectures available – qemu-system-x86_64 -cpu ?
-enable-kvm starts QEMU in KVM mode,
-m is for memory (RAM),
-smp is to specify the number of cores a VM could use.
For instance,
Qemu Ubuntu For Mac Virtualbox
Now, install an Operating System of your choice in disk image.
Qemu Ubuntu For Mac Installer
Run Virtual Machine (disk_image) through QEMU
To run a Virtual Machine, above code needs to be modified a bit. We would just remove the CD-ROM attached.
For instance,
In conclusion, we have discussed how to setup Virtual Machine using QEMU in Ubuntu distribution.
Qemu Kvm Mac
Note: For i386 architecture, we can use qemu-system-i386 command in place of qemu-system-x86_64.
