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
