[one-users] Defining disks (fs,mount,swap..)

[Ghazal Salehi]

Hi all

I have problem with defining disks in VM description file. Attributes
such as target, format, size...

I have tried two differnt images, ttylinux and centos.

This is the output of file ../ttylinux.img :

/srv/ttylinux.img: x86 boot sector, LInux i386 boot LOader; partition
1: ID=0x83, starthead 1, startsector 63, 81585 sectors, extended
partition table (last)\011

---------------------------------------------------------
output of file ../centos.img :
---------------------------------------------------------

/srv/cloud/one/1Gimage/euca-centos-5.3-x86_64/centos.orig.5-3.x86-64.img:
Linux rev 1.0 ext3 filesystem data (large files)

/dev/sda2         /mnt          ext3     defaults                   0 0

DISK = [ type = swap,
        size = 2048,
        taget = sda3
]

NIC    = [ NETWORK = "net201" ]

FEATURES=[ acpi="no" ]


I have gained the fstab files by mounting the images in a temporary
folder and then umount it again.
I don't know how to define mnt partition of centos image in
description file which is sd2 in fstab file.
How should I find out the sie of these partitions?

Thank you in advance for your help.
