Hi,

I am a newbie to OpenNebula, from the past one week i am trying to bring up a Virtual Machine from the template i created by using an ISO file (CENTOS-6.6-Minimal) and an empty datablock. I am doing it through Opennebula Sunstone & I used following website (http://www.whotouchedmygun.com/2014/03/17/create-a-vm-image-in-opennebula/) for the help. When i instantiated the VM, i am getting following error, Boot failed: Could not read from CDROM (code 0004) No bootable device.
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, if there is any alternate approach for the fulfillment of the same goal please suggest. Any solution from your side will be greatly appreciated.

Hi Vivek,

I opened a similar issue some days ago, Boot failed: not a bootable disk / no bootable device after installing a Ubuntu image through ON .

Basically, I needed to select as 1st boot “HD’ and as second boot “CDROOM” in the template created to read from the cdrom and install in the new image. I am not sure if you are getting the same issues but I hope it helps :smile:

Cheers,
Esteban
