Hi Flávio,<div><br></div><div>One of the new features introduced in the 2.0 version is the Image Repository [1]. If you want to give it a try, you can download the RC1 we have just released today [2].</div><div><br></div><div>
Using this repository, you can create an empty DATABLOCK image to store the data you mention. The changes made to the image are saved back to the repository once the VM is shutdown; and you can then then mount that image in any other virtual machine.</div>
<div><br></div><div>You will find useful the documentation for the new oneimage command [3], and the saveas option [4] for the onevm command. </div><div><br></div><div>I hope this meets your needs. If you need any more specific help, let us know.</div>

<div><div>Hello all,</div><div><br></div><div> I have an application that uses postgresql and I would like to create multiple instances of postgresql in different virtual machines. In this case, I want to persist the application data and use them in a new virtual machine (I do not want to replicate the virtual machine, just persist the data to use them in a new virtual machine).</div>
<div><br></div><div>There is a similar issue, but it was not answered.</div></div><div><a href="http://lists.opennebula.org/pipermail/users-opennebula.org/2009-August/000668.html" target="_blank">http://lists.opennebula.org/pipermail/users-opennebula.org/2009-August/000668.html<br clear="all">
