Hi Anoop,<div><br></div><div>we have figured out what's wrong. A while back we changed the $SED variable and to use by default the '-r' option (extended reg-exps), but that change broke the sed script which parses de VM ID which is passed to the tm_clone script. We have reported a bug and submitted a patch: <a href="http://dev.opennebula.org/issues/496">http://dev.opennebula.org/issues/496</a></div>
<div><br></div><div>In order to fix it manually, edit "$ONE_LOCATION/etc/tm_lvm/tm_lvmrc" and change this line:</div><div><div> echo $1 |$SED -e 's%^.*/\([^/]*\)/images.*$%\1%'</div></div><div>to this one:</div>
<div><div> echo $1 |$SED -e 's%^.*/([^/]*)/images.*$%\1%'</div></div><div><br></div><div>The link to the patch: <a href="http://dev.opennebula.org/projects/opennebula/repository/revisions/ef738d5d51cefff55f7ee2aec4f7721473ebeb0e/diff/src/tm_mad/lvm/tm_lvmrc">http://dev.opennebula.org/projects/opennebula/repository/revisions/ef738d5d51cefff55f7ee2aec4f7721473ebeb0e/diff/src/tm_mad/lvm/tm_lvmrc</a></div>
