Creating Custom Windows Images for Openstack

Setting up the KVM environment to create the custom images.

yum install kvm qemu-kvm python-virtinst libvirt libvirt-python virt-manager libguestfs-tools

Once the packages are installed we need to get the ISO’s.

For example are getting windows7 from the http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/
wget http://msft.digitalrivercontent.net/win/X17-24395.iso

Now we need the Virtio Driver’s so that windows can detect unsigned devices like linux from http://alt.fedoraproject.org/pub/alt/virtio-win/latest/

wget http://alt.fedoraproject.org/pub/alt/virtio-win/latest/virtio-win-0.1-81.iso

First Create the Disk on which the OS need to be installed

qemu-img create -f qcow2 -o preallocation=metadata windows.qcow2 20G

Start the KVM installation
/usr/libexec/qemu-kvm -m 2048 -smp 2 -cdrom X17-24395.iso -drive file=virtio-win-0.1-81.iso,index=3,media=cdrom -drive file= windows.qcow2,if=virtio,boot=off -boot d -vga std -k en-us -vnc 10.1.17.42:1 -usbdevice tablet

Connect to Installation

Once the above step is done you will be able to connect to VNC using 10.1.17.42:1
You will be connected to VNC and you will be at the installations screen. Click Next to continue

Windows-install00

Select Install option to continue with installation.

Windows-install01

While secting the Installation driver we need to load the driver, Select the load driveroption and load the driver from the Virto ISO we have mounted

Windows-install02

Continue with the installation

Windows-install04

Once you are done download the Cloud init for windows from

https://github.com/cloudbase/cloudbase-init
Once installation is completed load the computer with virto NIC with following Command

/usr/libexec/qemu-kvm -m 2048 -smp 2 -drive file=virtio-win-0.1-81.iso,index=3,media=cdrom -drive file=windows-7.qcow2,if=virtio -boot d -vga std -k en-us -vnc 10.1.17.42:1 -usbdevice tablet -net nic,model=virtio
Connect to VNC and add the Virto NIC Driver From Device manager

Windows-install06

Now install the Cloud-init and initialize the Image

Windows-install10

Enable RDP for the access.

Now the Image is ready for Use .

You can get the windows password by

nova get-password <instance ID> <ssh-key>

 

 

Nova Rule

nova secgroup-add-rule default tcp 3389 3389 0.0.0.0/0
