Thanks for the reply.
I am using Essex released version (2012-1 that was released in april). Here are
the outputs of nova command
$ nova volume-snapshot-list
+----+-----------+-----------+----------------------+------+
| ID | Volume ID | Status | Display Name | Size |
+----+-----------+-----------+----------------------+------+
| 2 | 4 | available | test-volume-snapshot | 1 |
+----+-----------+-----------+----------------------+------+
$ nova volume-snapshot-show 2
+---------------------+----------------------+
| Property | Value |
+---------------------+----------------------+
| created_at | 2012-05-19 01:22:57 |
| display_description | |
| display_name | test-volume-snapshot |
| id | 2 |
| size | 1 |
| status | available |
| volume_id | 4 |
+---------------------+----------------------+
However, when I try to attach the snapshot to a running instance , then I get
resource could not be found error. May be volume snapshot create did not
actually create a copy of the volume.

Hi VJ,
I believe you may have discovered a bug in the current version of
code. Are you using the latest Folsom version (ie devstack)? Check
your Horizon logs and you'll notice a number of errors when trying to
perform this operation. Perhaps some Horizon folks here have some
knowledge of this, otherwise I can look into it further next week and
file a bug if necessary.
Meanwhile, you can use python-novaclient to perform a 'nova
volume-snapshot-show' which is the information that would be reported
from the Horizon details page you're trying to retrieve.
Thanks,
John
