Hi Anoop,

we have figured out what's wrong. A while back we changed the $SED variable
and to use by default the '-r' option (extended reg-exps), but that change
broke the sed script which parses de VM ID which is passed to the tm_clone
script. We have reported a bug and submitted a patch:
http://dev.opennebula.org/issues/496

In order to fix it manually, edit "$ONE_LOCATION/etc/tm_lvm/tm_lvmrc" and
change this line:
    echo $1 |$SED -e 's%^.*/\([^/]*\)/images.*$%\1%'
to this one:
    echo $1 |$SED -e 's%^.*/([^/]*)/images.*$%\1%'

The link to the patch:
http://dev.opennebula.org/projects/opennebula/repository/revisions/ef738d5d51cefff55f7ee2aec4f7721473ebeb0e/diff/src/tm_mad/lvm/tm_lvmrc

Thanks for reporting this!

cheers,
Jaime
