Hi all,

i am using qcow2 internal snapshot , but it seems they are not working fine

Now to explain my scenario, I created qcow2 internal snapshot (qcow2 VM is on).

Now  i list the snapshot
-bash-4.1# qemu-img snapshot -l guestqcow2
Snapshot list:
ID        TAG                 VM SIZE                DATE       VM CLOCK
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
1         on3                       0 2012-03-22 13:45:26   00:00:00.000
2         on4                       0 2012-03-22 13:51:28   00:00:00.000

upto this point it is fine.
But now when i write something on the vm using dd command
Then

-bash-4.1# qemu-img snapshot -l guestqcow2

Snapshot list:
ID        TAG                 VM SIZE                DATE       VM CLOCK
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000
                                    0 1970-01-01 09:00:00   00:00:00.000


all my snapshots are gone. This is not a correct behavior
can any one explain why it is happening ?
and how can i fix it ?
