QEMU is a good virtual machine, the following nonsense does not say, directly said the installation process.

(1) Installing QEMU

Simulation arm needs to use Qemu-system-arm, install simulator

sudo apt-get install QEMU-KVM Qemu-kvm-extras

(2) Download kernel image. The following name is called Ubuntu.iso

(3) Create a virtual disk

sudo qemu-img create-f qcow2/opt/vm/ubuntu1010.img 10G

(4) Installing the virtual machine operating system

sudo qemu-system-x86_64-hda/opt/vm/ubuntu1010.img-cdrom/opt/iso/ubuntu.iso-boot d-m 1024-no-acpi

-HDA Specifies which virtual disk the hard disk is, with the ubuntu1010.img you just created

-cdrom specify CDROM is which, can use the ISO file, ye can use the machine optical drive, we choose to use the ISO file.

-BOOT specifies when booting from disk, hard drive, optical drive or network boot, we install the time choose to boot from the optical drive, so use D

-M virtual machine using the memory size, in megabytes, the default is 128MB, this 1024

-NO-ACPI because QEMU support is not good cause the system is very slow, so temporarily banned.

The installation Wizard will be installed after you enter.
