How to create a KVM Windows XP root filesystem for VNX

Create a basic Windows XP rootfs

  • Create the filesystem disk image:
    • qemu-img create -f qcow2 vnx_rootfs_kvm_winxp.qcow2 5G
  • Create the virtual machine with:
    • vnx --create-rootfs vnx_rootfs_kvm_winxp.qcow2 --install-media /almacen/iso/winxp.iso
  • Make a standard windows installation, naming the machine "winxp" and creating a "vnx" user.
  • After Windows XP instalation is finished:
    • Update it using "Windows update"
    • Disable screensaver
    • Disable Firewall
    • Install VNX autoconfiguration daemon by:
      • Executing on the host:
        • /usr/share/vnx/bin/vnx_update_aced WinXP /usr/share/vnx/aced/vnx-aced-win-0.1b.exe
      • Accessing virtual machine console and starting a windows file explorer, going to cdrom content (d: normally) and double clicking on vnx-aced-win-0.1b.exe file
    • Install TweakUI (http://download.microsoft.com/download/f/c/a/fca6767b-9ed9-45a6-b352-839afb2a2679/TweakUiPowertoySetup.exe) and disable autorun in all drives:
      • Expand the My Computer branch, then the AutoPlay branch, and then select Drives
      • Turn off the checkbox next to all drive letters
    • Activate windows by providing a license number
    • Optional: eliminate alert messages (at least firewall and antivirus ones) from "Control Panel-->Security Center-->Change alerts (left panel)"
    • Optional: install basic networking applications like an ssh client (i.e. putty), an scp client (i.e. winscp) or an X server (i.e Xming)
    • Configure static addresses in the four network interfaces and DISABLE all of them (necessary to speed up autoconfiguration). You can use, for example, the following script (setnetifs.bat):
      • netsh interface ip set address name="eth0" static 1.1.1.1 255.255.255.252
netsh interface ip set address name="eth1" static 1.1.1.5 255.255.255.252
netsh interface ip set address name="eth2" static 1.1.1.9 255.255.255.252
netsh interface ip set address name="eth3" static 1.1.1.13 255.255.255.252

      Note: this script supposes that the name of network interfaces has been changed to something rational like eth0, eth1, etc, instead of the original names "Conexión de área local X" which are unusable from a bat script due to the accents...

Known problems

  • Each time a vm starts, Windows finds new hardware and installs a driver for a standard RAM PCI controller. This fact slows down the boot process. To avoid it, just start the rootfilesystem once in direct mode to have windows detect the hardware and let the driver installed. For that purpose, you can use the following VNX scenario (xp.xml):
    • <?xml version="1.0" encoding="UTF-8"?>
<vnx xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="/usr/share/xml/vnx/vnx-1.95.xsd">
  <global>
    <version>1.92</version>
    <scenario_name>xp</scenario_name>
    <vm_mgmt type="none" />
  </global>
  <vm name="winxp" type="libvirt" subtype="kvm" os="windows">
    <filesystem type="direct">/usr/share/vnx/filesystems/vnx_rootfs_winxp</filesystem>
    <mem>512M</mem>
  </vm>
</vnx>

    Started with: 

    vnx -f xp.xml -v --create

    and stopped with: 

    vnx -f xp.xml -v --shutdown

    Note: never use not use "--destroy"option to stop a rootfilesystem use in direct mode: you will corrupt the filesystem.

Use sysprep to manage Windows XP activation

Install sysprep on the image

Generate the final image
