[one-users] Persistent image problem

[Stuart Kenny]

Hi, I have an image in a qcow datastore that I want to make persistent. 
The datastore configuration is below:

DATASTORE 102 INFORMATION 

ID             : 102
NAME           : ops-gw-qcow
USER           : oneadmin
GROUP          : ops
CLUSTER        : -
DS_MAD         : fs
TM_MAD         : qcow2
BASE PATH      : /var/lib/one/datastores/102

The image configuration is:

IMAGE 10 INFORMATION 

ID             : 10
NAME           : SL 5.8
USER           : oneadmin
GROUP          : ops
DATASTORE      : ops-gw-qcow
TYPE           : OS
REGISTER TIME  : 08/02 15:25:50
PERSISTENT     : Yes
SOURCE         : 
/var/lib/one/datastores/102/35b27eaab7c131bef8a2a3bd635cfc5d
FSTYPE         : save_as
SIZE           : 3775
STATE          : rdy
RUNNING_VMS    : 0

When I shutdown the VM I get the following log messages, which say that 
the image is being copied from the system datastore. The image in the 
system datastore is just a link however.

The original image is now overwritten with some small file, and I have 
lost my image:

ls -alh /var/lib/one/datastores/102/35b27eaab7c131bef8a2a3bd635cfc5d
-rw-r----- 1 oneadmin oneadmin 256K Aug 31 15:33 
/var/lib/one/datastores/102/35b27eaab7c131bef8a2a3bd635cfc5d

Is it possible to have a persistent qcow image?

Thanks,
Stuart.
