Windows image

Murano requires a Windows image in QCOW2 format to be built and uploaded into glance.

The easiest way to build a Windows image for murano is to build it on the host where your OpenStack is installed.

Prepare image builder host

Install KVM

Note

This guide was tested on Ubuntu Server 12.04 x64.

KVM is a default hypervisor in OpenStack, so our build scripts are targeted to this hypervisor only. It may change in the future, though.

Install KVM and some additional packages that are required by our scripts

# apt-get install qemu-kvm virtinst virt-manager

Check that your hardware supports hardware virtualization.

kvm-ok
# INFO: /dev/kvm exists
# KVM acceleration can be used

If your output differs, check that hardware virtualization is enabled in your BIOS settings. You also could try import KVM kernel module

sudo modprobe kvm-intel

or

sudo modprobe kvm-amd

It might be helpful to add an appropriate module name into /etc/modules file to auto-load it during system boot. Sometimes it is required on Ubuntu systems.

Configure shared resource

The murano image builder uses a shared folder located on the host system as an installation source for components. Makefile from the image builder will copy the required files to their locations, but you have to manually configure samba share. To do this, use the steps below.

• Install samba

  # apt-get install samba

• Create folder that will be shared

  # mkdir -p /opt/samba/share
  # chown -R nobody:nogroup /opt/samba/share

• Configure samba server (/etc/samba/smb.conf)

  ...
  [global]
     ...
    security = share
    ...
  [image-builder-share]
      comment = Image Builder Share
      browsable = yes
      path = /opt/image-builder/share
      guest ok = yes
      guest user = nobody
      read only = no
      create mask = 0755
  ...

• Restart samba services

  # service smbd restart
  # service nmbd restart

Additional tools

Tools from this section are not necessary to build an image. However, they may be helpful if you want to create an image with a different configuration.

Windows Assessment and Deployment Kit (ADK)

Windows ADK is required if you want to build your own answer files for auto unattended Windows installation.

Download it from http://www.microsoft.com/en-us/download/details.aspx?id=30652

Floppy image with unattended file

Floppy image with answer file for unattended installation is needed to automate Windows installation process.

• Create empty floppy image in your home folder

  mkdir ~/flp/files
  mkdir ~/flp/mnt

  dd bs=512 count=2880 if=/dev/zero of=~/flp/floppy.img
  mkfs.msdos ~/flp/floppy.img

• Mount the image

  mkdir ~/flp/mnt
  sudo mount -o loop ~/floppy.img ~/flp/mnt

• Download autounattend.xml.template file from https://github.com/openstack/murano-deployment/tree/master/contrib/windows/image-builder/lib/windowssetup/unattend/

  This folder contains unattended files for several Windows versions, choose one that matches your Windows version.

• Copy that file to mounted floppy image

  cp ~/autounattend.xml.template ~/flp/mnt/autounattend.xml

• Replace string %_IMAGE_BUILDER_IP_% in that file with 192.168.122.1

• Unmount the image

  sudo umount ~/flp/mnt

Build Windows image with murano

Build Windows image using image builder script

• Clone murano-deployment repository

  git clone git://git.openstack.org/openstack/murano-deployment.git

• Change directory to image-builder folder

  cd murano-deployment/contrib/windows/image-builder

• Create folder structure for image builder

  sudo make build-root

• Download build prerequisites, and copy them to correct folders

  • windows_installation_iso
  • required_prerequisites
  • optional_prerequisites (Optional)

• Test that all required files are in place

  sudo make test-build-files

• Get list of available images

  make

• Run image build process (e.g. to build Windows Server 2012)

  sudo make ws-2012-std

• Wait until process finishes

• The image file ws-2012-std.qcow2 should be stored inside /opt/image-builder/share/images folder.

Build windows image manually

Note

Please note that the preferred way to build images is to use Image Builder scripts, see build_image_using_image_builder_scripts

Get post-install scripts

There are a few scripts which perform all the required post-installation tasks.

They all are located in http://git.openstack.org/cgit/openstack/murano-deployment/tree/contrib/windows/image-builder/lib/windowssetup/scripts/

Note

There are subfolders for each supported Windows version. Choose one that matches Windows version you are building.

This folder contains several scripts

Script Name	Description
wpi.ps1	Handles component installation and system configuration tasks
Start-Sysprep.ps1	Prepares system to be syspreped (cleans log files, stops some services and so on), and starts sysprep
Start-AtFirstBoot.ps1	Performs basic after-installation tasks

Download these scripts and save them into /opt/image-builder/share/scripts

Create a VM

Now you need a virtual machine instance. There are two possible ways to create it - using CLI or GUI tools. We describe both in this section.

Using CLI Tools

1. Preallocate disk image

qemu-img create -f raw /var/lib/libvirt/images/ws-2012.img 40G

2. Start the VM

# virt-install --connect qemu:///system --hvm --name WinServ \
> --ram 2048 --vcpus 2 --cdrom /opt/samba/share/9200.16384.WIN8_RTM\
>.120725-1247_X64FRE_SERVER_EVAL_EN-US-HRM_SSS_X64FREE_EN-US_DV5.ISO \
> --disk path=/opt/samba/share/virtio-win-0.1-52.iso,device=cdrom \
> --disk path=/opt/samba/share/floppy.img,device=floppy \
> --disk path=/var/lib/libvirt/images/ws-2012.qcow2\
>,format=qcow2,bus=virtio,cache=none \
> --network network=default,model=virtio \
> --memballoon model=virtio --vnc --os-type=windows \
> --os-variant=win2k8 --noautoconsole \
> --accelerate --noapic --keymap=en-us --video=cirrus --force

Using virt-manager UI

1. Launch virt-manager from shell as root
2. Set a name for VM and select Local install media
3. Add one cdrom and attach Windows Server ISO image to it
4. Select OS type Windows
5. Set CPU and RAM amount
6. Deselect option Enable storage for this virtual machine
7. Add second cdrom for ISO image with virtio drivers
8. Add a floppy drive and attach our floppy image to it
9. Add (or create new) HDD image with Disk bus VirtIO and storage format RAW
10. Set network device model VirtIO
11. Start installation process and open guest vm screen through Console button

Install OS

Launch your virtual machine, connect to its virtual console and complete OS installation. At the end of this step you should have Windows Server system that you are able to log into.

Install prerequisites and murano

• Create folders where murano components will be installed

  Path	Description
  C:\Murano	Root directory for Murano
  C:\Murano\Agent	Murano Agent installation directory
  C:\Murano\Modules	PowerShell modules required by Murano
  C:\Murano\Scripts	PowerShell scripts and other files required by murano

• Open Explorer and navigate to \192.168.122.1share 192.168.122.1 is an IP address of KVM hypervisor assigned by default.

• Copy the murano agent files into C:MuranoAgent

• Copy CoreFunctions directory (entire directory!) into C:MuranoModules

• Install .NET 4.0

• Register the murano agent

  > cd C:\Murano\Agent
  > .\WindowsMuranoAgent.exe /install

• Change PowerShell execution policy to less restricted

  Set-ExecutionPolicy RemoteSigned

• Register CoreFunctions modules

  Import-Module C:\Murano\Modules\CoreFunctions\CoreFunctions.psm1 -ArgumentList register

• Install CloudInit

• Run Sysprep

  C:\Murano\Scripts\Start-Sysprep.ps1 -BatchExecution

• Wait until sysprep phase finishes and system powers off.

Convert the image from RAW to QCOW2 format

The image must be converted from RAW format to QCOW2 before being imported into glance.

# qemu-img convert -O qcow2 /var/lib/libvirt/images/ws-2012.raw \
> /var/lib/libvirt/images/ws-2012-ref.qcow2
