Hi Samuel,<br><br>It is safe to change the code, just a couple of comments:<br><br>Before stopping OpenNebula, check that there are not any VMs in a transient state (migrating, saving, etc.).<br>Then stop it, backup /var/lib/one (or $ONE_LOCATION/var), and use the '-k' option of install.sh to keep your current etc folder.<br>
<br>Also take into account that we haven't tested the proposed solution.<br><br>Regards.<br clear="all"><span style="border-collapse:collapse;color:rgb(136, 136, 136);font-family:arial, sans-serif;font-size:13px">--<br>

Thank you very much!<br><br>Is it safe to manually change the code and just perform a ./install.sh from the sources on a running installation? I'm using Mysql backend so I expect that the modification of the sources will only affect the compillation of the modified library and the rest will continue working ok.<br>
<br>Am I right?<br><br>I really appreciate the fast response.<br><font color="#888888"><br>Samuel Osorio.</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On 8 September 2011 12:20, Ruben S.

<br>
Yes you are right. There is an issue open [1]. We are planning to<br>
apply the proposed solution in that issue for 3.0 (i.e. clean-up will<br>
happen only when you issue a delete operation). I think this will<br>
address your use-case.<br>
