Editor to share with you a sample analysis of the production of win2003 virtio openstack images on centos7. I hope you will get something after reading this article. Let's discuss it together.

The kvm version is:

1. There are many ways to make a mirror image

Using virt-install

Using qemu-kvm (Or qemu-system_x86)

Using the virt-manage graphical interface

>.

Please refer to other blogs for virt-install installation.

As long as we explain how to use qemu-kvm to create an image, there are two ways for qemu-kvm to create an image:

> > first, mount win2003.iso directly in-cdrom mode, mount virtio-win-1.1.16.vfd in-fda mode and start it.

This article will not be explained in detail. For more details, please refer to the blog: http://www.linux-kvm.org/page/WindowsGuestDrivers/viostor/installation

> > second, the first step is to mount win2003.iso in-cdrom mode and start the installation in a non-virtio way. The second step is to start the image of the first step in virtio-win-0.1-74.iso in-cdrom mode, and then update the installation driver in win2003.

Note: virtio-win-0.1-74.iso download address: http://pan.baidu.com/s/1c0bNDXu (https://fedorapeople.org/groups/virt/virtio-win/deprecated-isos/archives/)

The following is the official start to create an image:

1. Download the iso image of win2003 (with address:)

Download virtio-win-0.1-74.iso (address: http://pan.baidu.com/s/1c0bNDXu)

3. Create a win2003 installation file (if qemu is not available, please install it yourself):

Qemu-img create-f qcow2 win2003virtiottx.qcow2 15000m

4. Start with qemu-kvm to create an image:

/ usr/libexec/qemu-kvm-m 2048-boot d-cdrom cn_win_srv_2003_r2_enterprise_with_sp2_vl_cd1_X13-46432.iso-drive file=win2003virtiottx.qcow2,if=virtio-net nic,model=virtio-usb-usbdevice tablet-vnc: 10

Next, explain the command in detail:

-boot d: indicates booting from CD. For more information, please refer to / usr/libexec/qemu-kvm-- help below:

-cdrom: Mount a CD disk

-drive file=: represents a disk file, and this time represents a blank disk (followed by if=virtio indicates that the bus communication mode of the disk file is virtio)

-net nic,model=virtio: indicates that the network card communicates with virtio driver

-usb-usbdevice tablet: add this parameter to make the mouse overlap (if not added, moving the mouse in the vnc will cause an offset)

-vnc: 10: indicates that the vnc address is ip:10 (where ip is the ip address of centos7)

For more information on qemu-kvm command parameters, please see http://linux.die.net/man/1/qemu-kvm

Note: many of the above parameters include virtio so that the system can automatically find the missing driver after the subsequent system installation.

If the initial image uses a non-virtio type of communication, then if you need to change it to virtio, you need to construct a virtio type.

For example, if you have been using an ide communication system disk, then if you directly change it to if=virtio, then you will not be able to identify the system because the driver has not been installed. So we can pass through

Mount another blank temporary disk, but the original system disk still uses ide, while the blank disk uses if=virtio. When booting into the system, install the virtio driver. Shutdown after installation.

Then, you don't need a blank disk, and directly modify the system disk to boot in if=virtio mode, and you can start normally (because the virtio driver has been installed in the system, you can recognize the boot system disk)

5. Use vncviewer to connect: (vncviewer download address: http://pan.baidu.com/s/1i3GUZAH)

Next, install the network card driver, which is not so easy to install. According to the official statement, the driver of windows 2003 should use the driver in the WNET directory in the virtio-win-0.1-30.iso file, but not in practice. Instead, use the drivers in the AMD64 directory under the XP directory. The installed ones are as follows.

This location, and the isos that were hosted here, are now deprecated.virtio-win builds are now distributed in a new location with a new iso filelayout. A yum repo is also provided.

No new isoswill be added here.

Restart the computer and win2003.qcow,if=virti0

Select wnet/x86
