Make OpenStack Windows mirroring-5 minutes a day to play with OpenStack (152)

This is the 2nd chapter in the OpenStack implementation experience sharing series.

OpenStack deploys instance through Glance mirroring, the previous section introduces the Linux image authoring method, Windows mirroring is very different from Linux, and today we take windows2008 as an example to discuss it in detail.

The image production steps are as follows:
1. Create and run the windows2008 KVM virtual machine
2. Installing the Virtio Drive
3. Installing Cloudbase-init
4. Other Custom work
5. Create a Glance image
6. Deploying new instance through mirroring

1. Create and run the Windows2008 KVM virtual machine

If there is a virt-manager, this step can be done in the graphical interface. Considering that not all cases have virt-manager, we are here to operate directly on the KVM host. The following steps are used to create a windows2008 virtual machine.

First create a 20G virtual disk as the Startup disk for the virtual machine:

Qemu-img create-f Qcow2/var/lib/libvirt/images/win2008r2sp1.qcow2 20G

Copy Virtual machine template

CP Template.xml Win2008r2sp1.xml

Template.xml How does this template come from? In fact, it is simple to dump the XML definition of an existing KVM virtual machine directly. Like what:

Virsh dumpxml [Vm-id] > Template.xml

Modify the following items in the Win2008r2sp1.xml:

Virtual machine Name

Virtual disks (previously created via QEMU-IMG) and boot ISO

Create a virtual machine

Virsh Define Win2008r2sp1.xml

Start a virtual machine

Virsh Start WIN2008R2SP1

Connecting virtual machines via VNC

Here 172.17.12.11 is the host IP, the port number is 2 (can be queried through Virsh vncdisplay). After the connection is successful, the virtual machine installation interface is displayed

The process of installing the operating system through the wizard is no longer mentioned. If the virtual machine does not restart automatically during the installation process, you can start the virtual machine with the following command

Virsh Start WIN2008R2SP1

After the installation is successful, set the IP address

2. Installing the Virtio drive

OpenStack uses Virtio disks and network cards by default, and Virtio performs well. Because Windows does not have its own Virtio driver, manual installation is required, as follows:

Add a virtio type of disk.

Virsh Edit Win2008r2sp1

Modify the current NIC device to Virtio.

Restart the operating system and install the Virtio driver.

3. Installing Cloudbase-init

Cloudbase-init enables the instance of a Windows mirroring deployment to automatically configure personalization information such as IP addresses. As with the Linux Cloud-init, the following illustrates the Cloudbase-init configuration method.

Download Cloudbase-init

https://cloudbase.it/cloudbase-init/#download

Installing Cloudbase-init in a virtual machine

Cloudbase-init Installer can be uploaded via Remote Desktop and installed

The system will shut down automatically.

4. Other Custom work

Restart the virtual machine to complete other customizations, such as installing some common software as needed. Now that the Windows image file is ready, the file path is

/var/lib/libvirt/images/win2008r2sp1.qcow2

5. Create a Glance image

The image creation method is the same as the previous Linux image

glance image-create--name "Windows R2 SP1"--file/var/lib/libvirt/images/win2008r2sp1.qcow2--disk-format Qcow2--container-format bare--is-public true--progress

6. Deploying new instance through mirroring

Click the "Start Cloud Host" button on the back of the image.

Give instance a name and click "Run", instance create successfully and assign to IP.

Click Instance Name.

Open the console.

In the VNC console you can see that the instance starts normally.

Click Administrator User

The first login requires a password change.

The above is the operation of customizing OpenStack Windows mirroring, and the next section discusses some of the experience and techniques used in mirroring.
