[one-users] persistent images

[Ruben Diez]

Hi:

I was try to make a VM that store its file systems after a shut-down, so 
the vm images templates are actualized to the last disk state whe the vm 
is shutdown...

According to the OpenNebula documentation (i think), this is done by 
declaring the images used by the VM as "persistent"

So, in my vm template i use some disks from the image repository:

[........]
DISK = [ image   = "NUBA_GENERICA" ]
DISK = [ image = "NUBA PRU DATA" ]
[........]

And these images are declared as "persistent":

[oneadmin at onesrv02 ]$ oneimage show NUBA_GENERICA

Nevertheless, when i make an "onevm shutdown <vm_id>", these disks are 
not saved.....

Where is my error???

Note: i'm using the ssh flavor of OpenNebula.... Perhaps the 
"persistent" stuff only works for the nfs flavor????

Regards....
