[one-users] how to change disk-snapshot from deferred to hot (--live) from CLI

[Fabella, Wesley]

I've recently started managing our virtual machines using OpenNebula in our
environment.  It runs on top of our CentOS KVM servers.

I have taken have already ran the cmd:

onevm disk-snapshot 37 0 X-test-20131018

which will take a deferred snapshot of the disk upon 'onevm shutdown' ...
problem is I have decided I want to do a "hot" live snapshot and receive
the following exception:

*oneadmin at headnode:~ $ onevm disk-snapshot --live 37 0 X-test-20131018*
*[VirtualMachineSaveDisk] Cannot use selected DISK. The DISK 0 is already
going to be saved.*

You will also see below VM no. 37 has deferred image to set to be no. 11.
 I have also deleted image no. 11 in hopes of free'ing VM no. 37 from
deferred image capture.  Turns out this wasn't the best option and I
probably should have went the Sunstone GUI route.

Any ideas here to free my VM no. 37 from wanting to save image as no. 11
which now does not exist?  At several glances I don't see a clear cut way
to back out of my situation in order to choose Hot (--live) snapshot.

Thanks in advance, (see output below pertaining to this issue)
