[one-users] VM Templates

[Daniel.MOLDOVAN at cs.utcluj.ro]

Hy,

I have encountered the same problem. Do not specify Kernel because this is
mainly used in conjunction with the XEN hypervisor and it indicates the
physical path to the HOST kernel used to boot the virtual machine, not of
the kernel inside the VM. So if the Host is using Ubuntu, only the Ubuntu
distributions can be loaded by using the Kernel attribute.

And about the no bootable device found, i have avoided it only by:
- defining also Image disk
 example: DISK = [type=cdrom ,
source=/home/utcn/Downloads/jeos-8.04.3-jeos-i386.iso, target=hdb]
- stating that ROOT=hdb and booting from the cdrom. From it i could
install the linux distribution on the "disk" device and then use it as a
normal boot device.


I think that because the virtual disk was not created by opennebula( i
used AQUEMU GUI), it did not recognized it properly in order to boot from
it.

P.S. If anywone has a more elegant solution to this "no bootable device
problem" problem fell free to share.

Thanks,
Daniel
