hi
i am also working with chandraprakash.
 
but when i mount and then try to do dd it does not run.
 
dd if=/dev/hda3 of=/tmp/nas

outputfile "of=" should be a file name whether already created or not created, it should not be a directory name.
Second thing did you have a write permission for the directory in which u r creating an output file., if not change the permssion using #chmod +w <dir>. Then try to create the output file using dd.


Thanks
Trilok

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

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_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
Trilok
