I followed the steps provided in the below link which will help me to convert from ISO to image.
After it finished the setup it launched the VNC viewer and stated showing the booted messages and in that I could login to the OS as well (but when I do ifconfig it was showing 127.0.0.1 only though I had configured to virbr0) .
I copied the image from /var/lib/libvirt/images/ttylinux.img to Opennebula controller(Virtual machine tool kit) .
And I deployed using Opennebula , but I cloudnt not do SSH to that so I tried with VNC viewer by connecting the running VM , in the viewer shows that
Booting from hard disk …
Boot failed : not a bootable disk
No bootable device.
How to copy the proper image ..? even I had tried clone the image thorugh virt-manager but same problem ..
