<font face="'courier new', monospace"><br></font></div><div><font face="arial, helvetica, sans-serif">If OpenNebula can't connect you'll probably notice some error messages on the logs. </font></div>
<div><font face="arial, helvetica, sans-serif">Take a look in var/oned.log and var/<vm id>/vm.log and post the errors, otherwise check the installation steps in the VMWare Driver section of the documentation.</font></div>
<div><font face="arial, helvetica, sans-serif">I remember that you have to configure a username and password in a file in order to let OpenNebula connect to hypervisors through virsh.</font></div>

<div><font face="arial, helvetica, sans-serif">I think that libvirt actually uses ver. 2.5 of those APIs.</font></div><div><font face="arial, helvetica, sans-serif">vSphere Client most probably connects to the hypervisor using those API (probably the latest version of the latter).</font></div>

<div>I noticed a serious problem about the usage of VMWare ESXi 4.1 and OpenNebula 2.0.1.</div>
<div>I'm actually using the VMWare driver addon which can be found on the opennebula website (ver. 1.0) and libvirt (ver. 0.8.7).</div>
<div>It happens that OpenNebula can't get information about the usage of resources on the cluster nodes.</div>
<div>By running 2 VM (each one requires 2 VCPU and 1 GB of memory) and executing some commands I get this output.</div>

<div>As you can see OpenNebula is unable to get correct information about the usage of resources on the cluster nodes.</div>
<div>As these informations are used by the VM scheduler, OpenNebula is unable to schedule the VM correctly.</div>
<div>I tried to create several VM and all of them were placed on the same host even if the latter was unable to satisfy the resource requirements of all the VMs.</div>
<div>I think that this problem is strongly related to libvirt as OpenNebula use it to recover information about hosts and vm.</div>
<div><br></div>
<div>Do you get the same behavior? Do you know if there is a way to solve this big issue?</div>
