Instead of manually typing in the commands, we can write our commands into a script file and run the script file each time we want to start our Android emulator. A script file is a file that contains all the terminal commands we want to execute. To avoid future frustration, we can create a script file. These numerous option flag are tedious to type in and often or not, we may forget one or two.

By adding a "-author" flag after the ls command, the result would include in the author of each files.įor the Qemu software to work with the Android OS image, we will need to add in specific option flags each time we execute qemu to start our emulator. For example, the ls command in Linux is the command to show a list of directory contents for the current working directory (folder).
In Linux systems, when a program is initiated to be executed in the terminal as a command, the user are often given the abilities to add different options when executing the command with different flags.

If you're not login to your machine as the root user, the terminal would prompt your to enter your computer password before the installation.

Installing Qemu is easy just type in the "sudo apt-get install" as shown in the picture above in the system terminal, the system would then automatically download and install the Qemu project for you. Since we are creating an Android emulator on a computer instead of installing one on a smartphone, we'll first have to install Qemu on our computer Qemu allows us to run an Android operating system image on our computer. With different CPU architectures, a smartphone operating system can't be directing installed and used on a normal computer. Just like cars and airplanes, while they all have engines to power their movements, their engines are not the same. Smartphones and computers are similar in that they both have CPU chips to process information, however, with the differences physical dimensions between the two devices, their CPU chips are not the same in terms of architecture. This ability presented by Qemu is crucial to the creation of an Android emulator on a computer. Such virtualization software, Qemu, enables the installation of different operating systems without the operating systems being directly linking to the hardware machine. So for example, when I create an arm machine, the XML generated lists armv7l.Qemu is a hardware virtualization software that obscures the actual physical hardware specifics of the machine from the higher level software programs.
So how can I know what architectures are available to send as an argument to getDomainCapabilities?Īside: to confuse things, virt-manager lists architectures that don't match the internal representation. The equivalent virsh command gives me a similar error. Libvirt.libvirtError: invalid argument: architecture from emulator 'armv7l' doesn't match given architecture 'x86_64' Raise libvirtError('virConnectGetDomainCapabilities() failed') For example: connection.getDomainCapabilities('/usr/bin/qemu-system-arm')įile "/./libvirt.py", line 4573, in getDomainCapabilities When I use the virsh command line or the Python API, I cannot get capabilities without providing an architecture. The Capabilities XML provides details on allowed values for these. There are also two optional attributes, arch specifying the CPU architecture to virtualization, and machine referring to the machine type. When creating a libvirt guest using XML, how do I determine what 'arch' values are valid for ? The problem is, for example, arm is invalid and must be armv7l instead.
