Vnx-rootfswin7

How to create a KVM Windows 7 root filesystem for VNX

• Create the filesystem disk image:

qemu-img create -f qcow2 vnx_rootfs_win7-base.qcow2 10GB

• Create a libvirt XML definition (rootfs_win7.xml) containing the virtual machine description:

<domain type='kvm'>
  <name>Win7</name>
  <memory>524288</memory>
  <vcpu>1</vcpu>
  <os>
    <type arch="i686">hvm</type>
    <boot dev='hd'/>
    <boot dev='cdrom'/>
  </os>
  <features>
     <pae/>
     <acpi/>
     <apic/>
  </features>
  <clock sync="localtime"/>
  <devices>
    <emulator>/usr/bin/kvm</emulator>
    <disk type='file' device='disk'>
      <source file='/usr/share/vnx/filesystems/vnx_rootfs_win7-base.qcow2'/>
      <target dev='hda'/>
    </disk>
    <disk type='file' device='cdrom'>
      <source file='/almacen/iso/win7.iso'/>
      <target dev='hdb'/>
    </disk>
    <interface type='network'>
      <source network='default'/>
    </interface>
    <interface type='network'>
      <source network='default'/>
    </interface>
    <interface type='network'>
      <source network='default'/>
    </interface>
    <interface type='network'>
      <source network='default'/>
    </interface>
    <serial type='pty'>
      <source path='/dev/pts/3'/>
      <target port='0'/>
    </serial>
    <graphics type='vnc'/>
  </devices>
</domain>

Note: change "source file=" lines to whatever fits your case (use full paths).

• Start the virtual machine with:

virsh create rootfs_win7.xml

• Open virtual machine console with:

virt-viewer Win7

Note: you also can access the console through vncviewer:

vncviewer localhost::5005

• After Windows 7 instalation is finished:
• Optional: autologin

Known problems

• After the Windows 7 virtual machine is shutdown, a blue screen of death (BSOD) appears...and the machine is rebooted. To stop the virtual machine, just type the following command when the BSOD appears:

virsh destroy Win7
