<div dir="ltr"><div><div><div><div><div><div>Dear OpenNebula Community,<br><br></div><div>1) To create VM using OpenNebula 3.6.0 in Ubuntu 12.04 with iSCSI datastore, I create Front-end, NodeServer and iSCSIHost (an iSCSI target VM created within the NodeServer. The IP of iSCSIHost is 192.168.1.7).<br>

<br></div><div>The required setup, configuration for Front-end, NodeServer and iSCSIHost looks fine.<br><br></div><div>The host,
image, vnet and datastore creation under NodeServer are ok (except of the VM creation in below 2) ), but when "oneimage show 0", can't see output of<div class="im">

only can see "SOURCE: /var/lib/images/win-xp.qcow2". <br><br>the
opennebula 3.6.0 used was downloaded in more than one year ago. is it the correct version of opennebula to use?<br>

the iSCSI INITIATOR is only installed in the NodeServer. the tgt (for tgt admin) is only installed in the
iSCSIHost, so the /etc/tgt/targets.conf is only in
the iSCSIHost.<br>
<br></div>From the result, it doesn't look like the Front-end and
NodeServer can well communicate with the iSCSIHost, can access the iSCSI storage partition created under the iSCSIHost target.<br><br></div></div>It is much appreciated if anyone can help with the above.<br><br></div>Thanks kindly,<br>
