it says gives error of as can run on directory
and when i try to create file in /tmp/nas it says permission denied.'

Then please contact your NAS admin to get the required write privileges.

    First You have to  mount NAS server to Linux machine, assume this
    is mounted to dir /mnt in linux machine.

    Now you could dd /de/hda3 to NAS server in a file backed VBD.

    # dd if=/dev/hda3 of=/mnt/hda.disk

    Now modify ur config file slightly as below.


    kernel = "/usr/lib/xen/boot/hvmloader"
    builder='hvm'
    memory = 1024
    name = "winxp"
    vcpus=1
    pae=0
    acpi=0
    apic=0
    cpus = ""
    vif = [ 'type=ioemu, bridge=xenbr0' ]
    #disk = [ 'phy:/dev/hda3,ioemu:hda,w' ]
    disk = [ 'file:/mnt/hda.disk,ioemu:hda,w' ]
    on_poweroff = 'destroy'
    on_reboot   = 'restart'
    on_crash    = 'destroy'
    device_model = '/usr/lib/xen/bin/qemu-dm'
    sdl=0
    vnc=1
    vncviewer=0
    stdvga=0
    serial='pty'
    ne2000=0
    usb=1
    usbdevice='tablet'

    and restart the domain.

    Other way u could populate the root file system in some NAS dir
    also. But this usage and reliability isa suspected.

    Thanks
