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 ?
