To<br>
add that parameters to network configuration you can do one of these<br>
things:<br>
<br>
* Create the network configuration in the base images manually and do<br>
not set network contextualization in OpenNebula so they are not<br>
overwritten.<br>
* Modify the context packages to add those parameters [1]<br>
<br>
For the third thing there is no way to do it. OpenNebula gets an IP<br>
from the network pool and assigns it to the NIC. There is no way to<br>
change it after it is selected and there is no external method of<br>
selecting the IP. What you can do is configure DHCP so it picks the<br>
same IP as OpenNebula had selected for the VM. The MAC addresses are<br>
generated from the MAC prefix and the IP, you can configure DHCP with<br>
those mac/ip pairs.<br>
<br>
MAC = PREFIX + IP in hex<br>
<br>
02:00:0a:00:00:01 = 02:00 + 10.0.0.1 (in hex is 0a:00:00:01)<br>
