qemantra Logo

Qemantra is a command-line tool for creating and managing QEMU Virtual Machines.

QEMU is better and sometimes faster than VirtualBox , but does not have any command-line central managing solution. This tool aims to manage and run your virtual machines using QEMU.



  • Create , list and run virtual machines.
  • Create configurations to run on demand.
  • Use features of QEMU like KVM , multiple architecture support etc.
  • Features like UEFI available in a simple flag!


Running a Virtual Machine


Run a machine with boot menu


Create a Machine


Create a Machine with Disk


Create a Image



Call qemantra in your terminal.

$ qemantra


Run qemantra check for checking for dependencies and configuration.

Highly recommended before using qemantra!.

Create Machine

The qemantra create-machine subcommand provides functionality to create machines.

Option Description
--name Name of the machine
--no-disk Don't create a disk
--disk-name Name of the disk(Not applicable when using no-disk)
--disk-size Size of the disk(Not applicable when using disk-size)
--cpu-cores Cores to provide to the RAM.
--mem-size RAM to provide to the VM

Running a machine

The qemantra run subcommand provides functionality to run a virtual machine.

Option Description
--name Name of the machine
--iso Path to the ISO(Relative path works)
--disk Disk name to add to boot order(Should be in default qemantra directory)
--externaldisk Path to a external disk to add to boot order(Any disk , not managed by qemantra)
--boot Boot options while starting the VM
--uefi Enable UEFI support(Requires OVMF to be installed)
--no-kvm Disables KVM(Enabled by default)

The boot options can be either menu which provides a menu to choose between boot devices. Or you can use iso option to directly boot the given iso.

Renaming a machine

The qemantra rename command is used to rename a existing virtual machine. If qemantra run has no arguments , it will execute the last machine which was booted.

List machines

Use qemantra list to list currently configured machines. Use --verbose option to list more information about the VM(Mem , Cpu etc).

You can list the images managed by qemantra by using --images option to qemantra list.

Installation ?

Installation using Go

You can install using Go by using

go install

This requires $GOBIN to be in our $PATH variable.

Installation using script

You can also use the autoinstall script. You should generally not execute scripts from the internet , so check the script

curl | bash

Installing manually

  • Download the static binary from the release page.
  • Move the binary to a location on your $PATH variable.

Roadmap ?

These are the major features planned to be added to qemantra. Other features are welcome to be discussed.

  • Running virtual machines
  • Creating virtual machines.
  • Can use memory and cpu cores.
  • Can use iso while running
  • Can use different disks while running
  • Can use external disk while running
  • Can use boot options
  • Make a auto install script.
  • Support UEFI using OVMF
  • Control logging functionality(-v / -vv and -vvv)
  • Add to major repositories(Debian , AUR , Gentoo)
  • Configuration changes using ENVIRONMENT VARIABLES
  • Multiple architecture support
  • Suppport easy clipboard sharing
  • Support easy shared folder support
  • List currently running machines.

Motivation ?

Virtualbox is good, but it has a QT interface and it's command line inteface is hectic at best. QEMU has no official (or good) frontend , the command line interface is mature , but has no central managing solution.

Qemantra aims to become a simple and convinient way to manage Virtual Machines. It is designed for the casual Virtualizer.
