[one-users] The vnet is not reachable

[Denis Ogura]

HI All,

Just want to share the solution of this problem with you guys (Thanks
Ettore)

1 - First of all, I didn`t define the context neither the target disk to be
booting up.
2 - I was using a Full Virtualization image, and trying to deploy via
OpenNebula a Paravirtualization.
3 - I downloaded a CentOS image Paravirtualization, and got to raise a new
VM using the Xen and also via OpenNebula (Thanks Ettore again).

So, everything is doing all right now. Going to start the scenarios runs and
then will write an paper down.

Thanks for all support.

Cheers

Denis
