[one-users] DHCP and OpenNebula

Fri May 9 01:12:14 PDT 2014

Hello Christophe,

If you really want to use DHCP in combination with OpenNebula I suggest you
take a look over omshell [1].

With a simple hook you could enter the required DHCP host entry via OMAPI
and your VM will pick it up at boot.

Best,
Valentin
