Make sure your scripts are placed in var/remotes/vmm just like the kvm etc... when start opennebula oned.log should show that these drivers are loaded.</div><div><br></div><div>When you add new host to opennebula your scripts are copied to the host. When you deploy a virtual machine on that host, Opennebula ssh to the host and call the 'deploy' script some arguments. Same for all the other actions. Documentation about this:</div><div><br></div><div>http://opennebula.org/documentation:rel3.8:devel-vmm</div><div><br></div><div>Now the tricky part would be to generate the appropiate lxc.xml for deployment. You would need to set the type attribute in the oned.conf vmm_lxc configuration to XML. The generated opennebula deployment file by opennebula will be simply the opennebula template in XML format. In your deploy script you should translate the information in it to whatever lxc libvirt driver needs.</div><div><br></div><blockquote style="margin: 0 0 0.80ex; border-left: #0000FF 2px solid; padding-left: 1ex"><div style="line-height:1.7;color:#000000;font-size:14px;font-family:arial"><div>2.

You can choose any language of your choice, as long as they can be executed in the remote host and perform the actions you want to perform everything is fine.</div><div><br></div><div>Perhaps looking at OpenNebula Virtualbox driver helps you to understand: https://github.com/hsanjuan/OneVBox (note that it doesn't use virsh though, but rather interpret the deployment XML file and perform the necessary actions to setup the VM as it indicates)</div><div><br></div><div>Regards,<br></div><br><div id="M2Signature"><div>-- </div><div>Hector Sanjuan<br>@hecsanjuan</div></div></body></html>
