Windows Image

Murano requires a Windows Image in QCOW2 format to be builded and uploaded into Glance.

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

Install Required Packages

Note

Please check that hardware virtualization supported and enabled in BIOS.

The following packages should be installed on any host which will be used to build Windows Image:

  • ipxe-qemu
  • kvm-ipxe
  • qemu-kvm
  • munin-libvirt-plugins
  • python-libvirt
  • virt-goodies
  • virt-manager
  • virt-top
  • virt-what
  • virtinst
  • python

On Ubuntu you could install them using the command below:

># apt-get install ipxe-qemu kvm-ipxe qemu-kvm virt-goodies \
           virtinst virt-manager libvirt0 libvirt-bin \
           munin-libvirt-plugins python python-libvirt \
           python-libxml2 python-minimal python-pycurl \
           python-pyorbit python-requests python-six \
           samba samba-common openssh-server virt-top virt-what

Configure Shared Resource

Configure samba based share.

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

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

...
[global]
   ...
   security = user
...
[share]
   comment = Deployment Share
   path = /opt/samba/share
   browsable = yes
   read only = no
   create mask = 0755
   guest ok = yes
   guest account = nobody
...

Restart services.

># service smbd restart
># service nmbd restart

Prerequisites

Download the files below and copy them into their places in your ${SHARE_PATH} folder (we usually use /opt/samba/share as ${SHARE_PATH}):

Additional Software

This section describes additional software which is required to build an Windows Image.

Windows ADK

Windows Assessment and Deployment Kit (ADK) for Windows® 8 is required to build your own answer files for auto unattended Windows installation.

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

PuTTY

PuTTY is a useful tool to manage your Linux boxes via SSH.

You can download it from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html.

Windows Server ISO image

We use the following Windows installation images:

VirtIO Red Hat drivers ISO image

Warning

Please, choose stable version instead of latest, We’ve got errors with unstable drivers during guest unattended install.

Download drivers from http://alt.fedoraproject.org/pub/alt/virtio-win/stable/

Floppy Image With Unattended File

Run following commands as root:

  1. Create emtpy floppy image in your home folder

    ># dd bs=512 count=2880 \
       if=/dev/zero of=~/floppy.img \
       mkfs.msdos ~/floppy.img
    
  2. Mount the image to /media/floppy

    ># mkdir /media/floppy mount -o loop \
       ~/floppy.img /media/floppy
    
  3. Download autounattend.xml file from https://raw.githubusercontent.com/stackforge/murano-deployment/master/image-builder/share/files/ws-2012-std/autounattend.xml.template

    ># cd ~
    ># wget https://raw.githubusercontent.com/stackforge/murano-deployment/master/image-builder/share/files/ws-2012-std/autounattend.xml.template
    
  4. Copy our autounattend.xml to /media/floppy

    ># cp ~/autounattend.xml /media/floppy
    
  5. Unmount the image

    ># umount /media/floppy
    

Build Windows Image (Automatic Way)

  1. Clone murano-deployment repository

    ># git clone git://github.com/stackforge/murano-deployment.git
    
  2. Change directory to murano-deployment/image-builder folder.

  3. Create folder structure for image builder

    ># make build-root
    
  4. Create shared resource

    Add to /etc/samba/smb.conf.

    [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.

    ># restart smbd && restart nmbd
    
  5. Test that all required files are in place

    ># make test-build-files
    
  6. Get list of available images

    ># make
    
  7. Run image build process

    ># make ws-2012-std
    
  8. Wait until process finishes

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

Build Windows Image (Manual Way)

Warning

Please note that the preferred way to build images is to use Automated Build described in the previous chapter.

Get Post-Install Scripts

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

Package installation tasks are performed by script named wpi.ps1.

Download it from https://raw.github.com/stackforge/murano-deployment/master/image-builder/share/scripts/ws-2012-std/wpi.ps1

Note

There are a few scripts named wpi.ps1, each supports only one version of Windows image. The script above is intended to be used to create Windows Server 2012 Standard. To build other version of Windows please use appropriate script from scripts folder.

Clean-up actions to finish image preparation are performed by Start-Sysprep.ps1 script.

Download it from https://raw.github.com/stackforge/murano-deployment/master/image-builder/share/scripts/ws-2012-std/Start-Sysprep.ps1

These scripts should be copied to the shared resource folder, subfolder Scripts.

Create a VM

This section describes steps required to build an image of Windows Virtual Machine which could be used with Murano. There are two possible ways to create it - from CLI or using GUI tools. We describe both in this section.

Note

Run all commands as root.

Way 1: Using CLI Tools

This section describes the required step to launch a VM using CLI tools only.

  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
    

Way 2: Using virt-manager UI

A VM also could be lauched via GUI tools like virt-manager.

  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

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
