This page describes how to set up Funtoo Linux to run Windows 7 Professional 32-bit within a KVM virtual machine. KVM is suitable for running Windows 7 for general desktop application use. It does not provide 3D support, but offers a nice, high-performance virtualization solution for day-to-day productivity applications. It is also very easy to set up.
* "CUPS is the standards-based, open source printing system developed by Apple Inc. for OS X® and other UNIX®-like operating systems. CUPS uses the Internet Printing Protocol (IPP) to support printing to local and network printers." ([http://www.cups.org CUPS homepage])
+
  
* "CUPS provides a mechanism that allows print jobs to be sent to printers in a standard fashion. The print-data goes to a scheduler which sends jobs to a filter system that converts the print job into a format the printer will understand. The filter system then passes the data on to a backend—a special filter that sends print data to a device or network connection. The system makes extensive use of PostScript and rasterization of data to convert the data into a format suitable for the destination printer."

 +
== Kernel Setup ==
 +
 
 +
If you are using an automatically-built kernel, it is likely that KVM is already available.
 +
 
 +
If you are compiling your own kernel, the following kernel config parameters should be enabled (this is based on a 3.x kernel):
 +
 
 +
Under <tt>Processor type and features</tt>, enable <tt>Paravirtualized Guest Support</tt>. Under the <tt>Paravirtualized Guest Support</tt> menu, enable any options related to KVM, such as <tt>KVM paravirtualized clock</tt> and in particular <tt>KVM Guest Support</tt>.
 +
 
 +
Under the <tt>Virtualization</tt> category from the main kernel config menu, enable <tt>Kernel-based Virtual Machine (KVM) support</tt>, and enable at least one type of KVM, either for Intel or AMD processors. It is also recommended to enable <tt>Host kernel acceleration for virtio net</tt>.
 +
 
 +
You can use modules or build these parts directly into the kernel. Build your new kernel and modules, and reboot.
 +
 
 +
== Emerge Qemu ==
 +
 
 +
First, add the following USE flags to <tt>/etc/make.conf</tt>
 +
 
 +
<pre>
 +
USE="sdl usbredir"
 +
</pre>
 +
 
 +
Now, emerge qemu:
 +
 
 +
<console>
 +
# ##i##emerge -av qemu
 +
</console>
 +
 
 +
After <tt>qemu</tt> and its dependencies have been installed, you are now ready to start setting up your Windows 7 environment.
 +
 
 +
== Windows 7 ISO Images ==
 +
 
 +
In this tutorial, we are going to install Windows 7 Professional, 32-bit Edition. Microsoft provides a free download of the ISO DVD image, but this does require a valid license key for installation. You can download Windows 7 Professional, 32 bit at the following location:
 +
 
 +
http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65804/X15-65804.iso
 +
 
 +
In addition, it's highly recommended that you download "VirtIO" drivers produced by Red Hat. These drivers are installed under Windows and significantly improve Windows 7 network and disk performance. You want to download the ISO file (not the ZIP file) at the following location:
 +
 
 +
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/
 +
 
 +
== Create Raw Disk ==
 +
 
 +
In this tutorial, we are going to create a 30GB raw disk image for Windows 7. Raw disk images offer better performance than the commonly-used QCOW2 format. Do this as a regular user:
 +
 
 +
<console>
 +
$ ##i##cd
 +
$ ##i##qemu-img create -f raw win7.img 30G
 +
</console>
 +
 
 +
We now have an empty virtual disk image called <tt>win7.img</tt> in our home directory.
 +
 
 +
== QEMU script ==
 +
 
 +
Now, we'll create the following script to start our virtual machine and begin Windows 7 installation. Note that this script assumes that the two ISO files downloaded earlier were placed in the user's <tt>Downloads</tt> directory. Adjust paths as necessary if that is not the case. Also be sure to adjust the following parts of the script:
 +
 
 +
* Adjust the name of <tt>VIRTIMG</tt> to match the exact name of the VirtIO ISO image you downloaded earlier
 +
* Adjust the <tt>smp</tt> option to use the number of CPU cores and threads (if your system has hyperthreading) of your Linux system's CPU.
 +
 
 +
Use your favorite text editor to create the following script. Name it something like <tt>vm.sh</tt>:
 +
 
 +
<syntaxhighlight lang="bash">
 +
#!/bin/sh
 +
export QEMU_AUDIO_DRV=alsaDISKIMG=~/win7.img
 +
WIN7IMG=~/Downloads/X15-65804.iso
 +
VIRTIMG=~/Downloads/virtio-win-0.1-74.iso
 +
qemu-kvm --enable-kvm -drive file=${DISKIMG},if=virtio -m 2048 \
 +
-net nic,model=virtio -net user -cdrom ${WIN7IMG} \
 +
-drive file=${VIRTIMG},index=3,media=cdrom \
 +
-rtc base=localtime,clock=host -smp cores=2,threads=4 \
 +
-usbdevice tablet -soundhw ac97 -cpu host -vga vmware
 +
</syntaxhighlight>
 +
 
 +
Now, make the script executable:
 +
 
 +
<console>
 +
$ ##i##chmod +x vm.sh
 +
</console>
 +
 
 +
Here is a brief summary of what the script does. It starts the <tt>qemu-kvm</tt> program and instructs it to use KVM to accelerate virtualization. The system disk is the 30GB raw image you created, and we tell QEMU to use "virtio" mode for this disk, as well as "virtio" for network access. This will require that we install special drivers during installation to access the disk and enable networking, but will give us better performance.
 +
 
 +
To assist us in installing the VirtIO drivers, we have configured the system with two DVD drives -- the first holds the Windows 7 installation media, and the second contains the VirtIO driver ISO that we will need to access during Windows 7 installation.
 +
 
 +
The <tt>-usbdevice tablet</tt> option will cause our mouse and keyboard interaction with our virtual environment to be intuitive and easy to use.
 +
 
 +
== Starting Windows 7 Installation ==
 +
 
 +
Now, it's time to start Windows 7 installation. Run <tt>vm.sh</tt> as follows:
 +
 
 +
<console>
 +
$ ##i##./vm.sh
 +
</console>
 +
 
 +
Windows 7 installation will begin. During the installation process, you will need to enter a valid license key, and also load ''both'' VirtIO drivers from Red Hat when prompted (Browse to the second DVD, then win7 directory, then x86).
 +
 
 +
After some time, Windows 7 installation will complete. You will be able to perform Windows Update, as by default, you will have network access if your host Linux system has network access.

This page describes how to set up Funtoo Linux to run Windows 7 Professional 32-bit within a KVM virtual machine. KVM is suitable for running Windows 7 for general desktop application use. It does not provide 3D support, but offers a nice, high-performance virtualization solution for day-to-day productivity applications. It is also very easy to set up.

Contents

Introduction

KVM is a hardware-accelerated full-machine hypervisor and virtualization solution included as part of kernel 2.6.20 and later. It allows you to create and start hardware-accelerated virtual machines under Linux using the QEMU tools.

Windows 7 Professional 32-bit running within qemu-kvm

Kernel Setup

If you are using an automatically-built kernel, it is likely that KVM is already available.

If you are compiling your own kernel, the following kernel config parameters should be enabled (this is based on a 3.x kernel):

Under Processor type and features, enable Paravirtualized Guest Support. Under the Paravirtualized Guest Support menu, enable any options related to KVM, such as KVM paravirtualized clock and in particular KVM Guest Support.

Under the Virtualization category from the main kernel config menu, enable Kernel-based Virtual Machine (KVM) support, and enable at least one type of KVM, either for Intel or AMD processors. It is also recommended to enable Host kernel acceleration for virtio net.

You can use modules or build these parts directly into the kernel. Build your new kernel and modules, and reboot.

Emerge Qemu

First, add the following USE flags to /etc/make.conf

USE="sdl usbredir"

Now, emerge qemu:

# emerge -av qemu

After qemu and its dependencies have been installed, you are now ready to start setting up your Windows 7 environment.

Windows 7 ISO Images

In this tutorial, we are going to install Windows 7 Professional, 32-bit Edition. Microsoft provides a free download of the ISO DVD image, but this does require a valid license key for installation. You can download Windows 7 Professional, 32 bit at the following location:

http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65804/X15-65804.iso

In addition, it's highly recommended that you download "VirtIO" drivers produced by Red Hat. These drivers are installed under Windows and significantly improve Windows 7 network and disk performance. You want to download the ISO file (not the ZIP file) at the following location:

http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/

Create Raw Disk

In this tutorial, we are going to create a 30GB raw disk image for Windows 7. Raw disk images offer better performance than the commonly-used QCOW2 format. Do this as a regular user:

$ cd
$ qemu-img create -f raw win7.img 30G

We now have an empty virtual disk image called win7.img in our home directory.

QEMU script

Now, we'll create the following script to start our virtual machine and begin Windows 7 installation. Note that this script assumes that the two ISO files downloaded earlier were placed in the user's Downloads directory. Adjust paths as necessary if that is not the case. Also be sure to adjust the following parts of the script:

  • Adjust the name of VIRTIMG to match the exact name of the VirtIO ISO image you downloaded earlier
  • Adjust the smp option to use the number of CPU cores and threads (if your system has hyperthreading) of your Linux system's CPU.

Use your favorite text editor to create the following script. Name it something like vm.sh:

#!/bin/sh
export QEMU_AUDIO_DRV=alsaDISKIMG=~/win7.img
WIN7IMG=~/Downloads/X15-65804.iso
VIRTIMG=~/Downloads/virtio-win-0.1-74.iso
qemu-kvm --enable-kvm -drive file=${DISKIMG},if=virtio -m 2048 \
-net nic,model=virtio -net user -cdrom ${WIN7IMG} \
-drive file=${VIRTIMG},index=3,media=cdrom \
-rtc base=localtime,clock=host -smp cores=2,threads=4 \
-usbdevice tablet -soundhw ac97 -cpu host -vga vmware

Now, make the script executable:

$ chmod +x vm.sh

Here is a brief summary of what the script does. It starts the qemu-kvm program and instructs it to use KVM to accelerate virtualization. The system disk is the 30GB raw image you created, and we tell QEMU to use "virtio" mode for this disk, as well as "virtio" for network access. This will require that we install special drivers during installation to access the disk and enable networking, but will give us better performance.

To assist us in installing the VirtIO drivers, we have configured the system with two DVD drives -- the first holds the Windows 7 installation media, and the second contains the VirtIO driver ISO that we will need to access during Windows 7 installation.

The -usbdevice tablet option will cause our mouse and keyboard interaction with our virtual environment to be intuitive and easy to use.

Starting Windows 7 Installation

Now, it's time to start Windows 7 installation. Run vm.sh as follows:

$ ./vm.sh

Windows 7 installation will begin. During the installation process, you will need to enter a valid license key, and also load both VirtIO drivers from Red Hat when prompted (Browse to the second DVD, then win7 directory, then x86).

After some time, Windows 7 installation will complete. You will be able to perform Windows Update, as by default, you will have network access if your host Linux system has network access.

Enjoy your virtualized Windows 7 system!
