<P> </P>
<P>Could you tell which version of OpenNebula you're running ?</P>
<P>Could you paste the template you're using to instantiate your VM ?</P>
<P> </P>
<P>If you just want to run a basic CentOS image, you can use the one available on OpenNebula's Marketplace (available from Sunstone).</P>
<P> </P>
<P>Enjoy</P>

<DIV>Hi,</DIV>
<DIV><BR></DIV>
<DIV>I am a newbie to OpenNebula, from the past one week i am trying to bring up a Virtual Machine by using an ISO file (CENTOS-6.6-Minimal) and an empty datablock. I was doing it through Opennebula Sunstone & I was referring following website (<A class=blue href="http://www.whotouchedmygun.com/2014/03/17/create-a-vm-image-in-opennebula/" target=_blank>http://www.whotouchedmygun.com/2014/03/17/create-a-vm-image-in-opennebula/</A>) for the help. But after completion when i tried to start the VM i am getting following error, Boot failed: Could not read from CDROM (code 0004) No bootable device. </DIV>
<DIV>In my case KVM Hypervisor,Opennebula Server all are on the same server and storage is local hard disk. Please suggest me if anything i need to modify. I couldn't get a proper solution on my internet search, or if there is any other alternate approach for the fulfillment of the same goal please suggest. Any solution from your side will be greatly appreciated.</DIV>
