Hi,
The VM needs to have the contextualization scripts configured to be run at
start-up. The important one is vmcontext, it reads the MAC address and sets
the IP from it: the assigned IP 10.112.10.37 is 0a:70:0a:25 in hexadecimal.
The CONTEXT section in the VM template is completely optional, it is not
required for the IP setup.
If you continue having troubles, you can try to log into your VM using VNC
and check if the VM is really running and booted successfully. Try to
execute the vmcontext script as root, if the IP is then configured, you may
need to change the runlevel where you put it.
Regards
