I was really hoping that the VM provided there
http://www.opennebula.org/documentation:rel2.0:vmg works. So I think (and
hope) that I have a configuration issue or I do not understand this part.
I removed all the context section since I do not understand this statement
"You should choose the ip_public field to be an IP which does not match any
of the predefined LEASES of small_network.net (only for demonstration
purposes)."
What is the goal of this ip_public field if ONE takes the IP from the LEASES
list?
If the context is not set, what will be the IP address of the VM? The one
from the leases list?
If the context is set, what is the role of the public_ip field?
Can someone give me details on this part? In
http://www.opennebula.org/documentation:rel2.0:vmg there are two different
IP addresses with and without context...
