Workstation setup

  • Ubuntu 16.04
  • sudo apt install virtinst virt-manager qemu-kvm
  • sudo usermod -a -G libvirtd <username>

where username is the user you will run these steps as.

Stemcell creation

  1. Download a Windows 2012R2 iso (we will call it windows2012-disk.iso in these instructions)

  2. Download the Windows virtio drivers

  3. Create a qcow2 disk image

    qemu-img create -f qcow2 ws2012.qcow2 30G

  4. Start a windows VM with the qcow2 disk, windows installer, and virtio drivers attached:

    virt-install --connect qemu:///system \
  --name ws2012 --ram 4096 --vcpus 2 \
  --network network=default,model=virtio \
  --disk path=ws2012.qcow2,format=qcow2,device=disk,bus=virtio \
  --disk path=~/Downloads/windows2012-disk.iso,device=cdrom \
  --disk path=~/Downloads/virtio-win-0.1.126.iso,device=cdrom \
  --vnc --os-type windows --os-variant win2k12

  5. Install windows on the qcow2 disk

  • Pick Windows Server 2012 R2 Standard (Server with a GUI)
  • Custom install
  • Click Load driver -> Browse, select E:\viostor\2k12R2\amd64, select the only driver, and click Next
  • Continue and finish install
  1. Install required Openstack drivers and Cloudbase-init
  • Open a powershell terminal. Install the redhat ethernet driver:
pnputil -i -a E:\NetKVM\2k12R2\amd64\netkvm.inf
  • Download and Install Cloudbase-init:
C:\Invoke-WebRequest -UseBasicParsing https://cloudbase.it/downloads/CloudbaseInitSetup_Stable_x64.msi -OutFile cloudbaseinit.msi
.\cloudbase-init.msi

  • For cloudbase-init installer, choose username Administrator, uncheck Use metadata password, select COM1 for Serial port for logging

  • Do NOT check boxes to run sysprep or shutdown. Finish install.

  • OPTIONAL Set password for administrator: If you would like to log in as Administrator to the stemcell for debugging (or anything else), run the following modification to the default unattend.xml for cloudbase-init:

New-Item -ItemType "file" -path "C:\Program Files\Cloudbase Solutions\Cloudbase-Init\LocalScripts\setup-admin.ps1" -Value @'
$NewPassword = "My-Admin-Password!"
$AdminUser = [ADSI]"WinNT://${env:computername}/Administrator,User"
$AdminUser.SetPassword($NewPassword)
$AdminUser.passwordExpired = 0
$AdminUser.setinfo()
'@

New-Item -ItemType "file" -path "C:\Program Files\Cloudbase Solutions\Cloudbase-Init\conf\Unattend.xml" -Force -Value @"

  1. Install Bosh Agent and CF dependencies

  • Download agent.zip and bosh-psmodules.zip from the latest bosh-windows-stemcell-builder release:

    Invoke-WebRequest -uri https://github.com/cloudfoundry-incubator/bosh-windows-stemcell-builder/releases/download/1056.0/bosh-psmodules.zip -outfile bosh-psmodules.zip
Invoke-WebRequest -uri https://github.com/cloudfoundry-incubator/bosh-windows-stemcell-builder/releases/download/1056.0/agent.zip -outfile agent.zip

Make sure to replace 1056 with the latest stemcell version.

  • Extract bosh-psmodules.zip and move all the BOSH.* directories into C:\Program Files\WindowsPowerShell\Modules

  • Install the Agent and CF dependencies:

    Install-CFFeatures
Protect-CFCell
Install-Agent -IaaS openstack -agentZipPath <path-to-agent.zip>

Note: To make sure you have the proper .NET Framework version(s) installed, follow this guide

  • Optionally apply security policies as described in [create-manual-vsphere-stemcells.md]

  1. Complete sysprep in the VM

    C:\Windows\System32\Sysprep\sysprep.exe /oobe /generalize /quiet /shutdown /unattend:'C:\Program Files\Cloudbase Solutions\Cloudbase-Init\conf\Unattend.xml'

  2. Package the qcow2 disk into a stemcell

    mv ws2012.qcow2 root.img
tar czf image root.img
image_sha=$(sha1sum image | awk '{ print $1 }')
version='7777.7' # Use whatever version you'd like
echo "---
name: bosh-openstack-kvm-windows-go_agent
version: '$version'
bosh_protocol: 1
sha1: $image_sha
operating_system: 'windows2012R2'
cloud_properties:
  name: bosh-openstack-kvm-windows-go_agent
  version: '$version'

  container_format: bare

tar czf openstack-stemcell.tgz stemcell.MF image
