In this article I will show how to install a Windows 7 64-Bit image on OpenStack. For different versions of Windows watch out for the corresponding notes in the article.<\/p>\n

Prepare the Installation<\/h2>\n

Ubuntu, QEMU and KVM<\/h3>\n

Creating a Windows image from scratch is best done by using a linux distribution to do the installation process. To create the image we will use QEMU and\u00a0KVM<\/a>\"\", which is a full virtualization solution for Linux. On Ubuntu you can install KVM using the following commands in the shell:<\/p>\n

$ sudo apt-get update\r\n$ sudo apt-get install qemu-system-x86\r\n$ sudo apt-get install qemu-kvm\r\n$ sudo apt-get install virt-manager\r\n$ sudo apt-get install libvirt-bin libvirt-doc<\/pre>\n
If you are working on a Windows or Mac machine you can not use a Linux-VM to do the installation. The VM will not be able to use the hardware virtualization extension (Intel VT or AMD-V).<\/p>\n
<\/p>\n
ISO Files<\/h3>\n
To store the iso files we create a directory called “iso” in the home directory. That step is not mandatory, but will help you to use the following commands.<\/p>\n
$ mkdir ~\/iso<\/pre>\n
Windows ISO<\/h4>\n
First you need an iso-file of Windows. Download a Windows ISO-File from your preferred site; e.g. a link for Windows 7 Professional can be found on the\u00a0community website of microsoft<\/a>\"\"). Move the iso file in the “iso” directory.<\/p>\n
As for all Microsoft products you need to buy a license key to use the operating system, even if it is used as a VM.<\/p>\n
VirtIO ISO<\/h4>\n
The tricky part to create a Windows image for OpenStack is to use the proper driver for the virtualized hardware components like the IDE controller and the network interface. Download the latest digital signed\u00a0VirtIO drivers<\/a>\"\"\u00a0from Fedora and move it to the iso directory.<\/p>\n
Create the image<\/h2>\n
Create the container file<\/h3>\n
Now after doing all preparation steps we can create the image. This image file will hold the Windows installation. Like before you could create a directory called “image” on your home directory to store the image file.<\/p>\n
$ mkdir ~\/image\r\n$ cd ~\/image<\/pre>\n
Use the following QEMU command to create the image file.<\/p>\n
$ qemu-img create -f qcow2 win7_sp1_x64_en_vlk.qcow2 100G<\/pre>\n
That command will create a image with\u00a0qcow2<\/b>\u00a0as format,\u00a0win7_sp1_x64_en_vlk.qcow2<\/b>\u00a0as a name and with a capacity of\u00a0100GB<\/b>. At the moment that is only a container for the installation.<\/p>\n
Start the VM<\/h3>\n
The next step is to launch a VM with KVM and start the Windows installation.<\/p>\n
$ sudo kvm -m 2048 -drive file=~\/iso\/windows_7_professional.iso,index=1,media=cdrom -drive file=~\/image\/win7_sp1_x64_en_vlk.qcow2,if=virtio -drive file=~\/iso\/virtio-win-0.1-74.iso,index=3,media=cdrom -net nic,model=virtio -net user -nographic -vnc :9 -usbdevice tablet<\/pre>\n
That command will start a VM with following settings:<\/p>\n
