[one-users] Missing log when no error happens

[Ruben S. Montero]

So, your proposal is to have, all messages as in:

    [TM][I]: clone: Cloning
/var/lib/one/datastores/1/e72972d1dc14203d83520f9ae6395d94 in
yggdrasil:/var/lib/one//datastores/0/15/disk.1

This is pre-pend with the "clone:" string, right? If this is the case, this
could be done in the core as:

   [TM][I]: <<<<<< ERROR IN CLONE >>>>>>>>>
   [TM][I]: Command execution fail: /var/lib/one/remotes/tm/qcow2/clone
yggdrasil:/var/lib/one/datastores/1/e72972d1dc14203d83520f9ae6395d94
yggdrasil:/var/lib/one//datastores/0/15/disk.1 15 1
    [TM][I]: clone: Cloning
/var/lib/one/datastores/1/e72972d1dc14203d83520f9ae6395d94 in
yggdrasil:/var/lib/one//datastores/0/15/disk.1
...
   [TM][I]: <<<<<< ERROR IN CLONE >>>>>>>>>


What do you think?
