I can post the VM template content on monday. However, as far as I remember, the vm template was really simple:<div><font class="Apple-style-span" face="'courier new', monospace">NAME="Debian"</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">VCPU= 2</font></div><div><font class="Apple-style-span" face="'courier new', monospace">MEMORY=1024</font></div><div><font class="Apple-style-span" face="'courier new', monospace">DISK=[IMAGE="Debian5-i386"]</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace">OS=[ARCH=i686]</font></div><div><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div><font class="Apple-style-span" face="arial, helvetica, sans-serif">The VMs can boot and run, I can log on console through vSphere Client on the newly created VMs.</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div><font class="Apple-style-span" face="arial, helvetica, sans-serif">I noticed that if you don't declare the number on VCPU the VM doesn't get scheduled on a cluster node. This option seems mandatory but I didn't find any mention about it on the documentation.</font></div>
<div><font class="Apple-style-span" face="arial, helvetica, sans-serif">Another thing that seems mandatory is declaring the cpu architecture as i686, otherwise OpenNebula will return error when writing the deployment.0 file.</font></div>

Hi,<div><br></div><div>I am not sure this is related to the VMware monitoring... Can you send the VM Templates?</div><div><br></div><div>Thanks</div><div><br></div><div>Ruben<br><br><div class="gmail_quote"><div><div></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>
