[one-users] Network provisioning

[Javier Fontan]

Hello,

The error you have is that you have not created a network called
"VNET". Check http://opennebula.org/documentation:rel1.4:vgg and
create a network with the desired name before submitting a VM.

Then there are several ways to configure the IP inside the VM, these are:

  a) DHCP server
  b) Contextualization scripts that set the IP using the MAC address:
http://opennebula.org/documentation:rel1.4:vgg
  c) Contextualization image with IP network configuration values:
http://opennebula.org/documentation:rel1.4:cong and
http://opennebula.org/documentation:rel1.4:vmg
  d) Fixed configuration inside VM image

You have to pick the one that suits your needs. For us, the most
flexible way is option "c".

Bye
