Dear Daniel,

Opennebula friends, is that sequence correct?
1. OpenNebula generates a MAC, based on  MAC_PREFIX   = "02:00" from
oned.conf;
2. This MAC is passed to VM image(here is the doubt: How?)
3. vmcontext.sh runs and configures IP based on generated MAC address.

Steps 1 and 3 are working correctly, but step 2 not yet.

So, how this link between opennebula and VM image is performed?
How MAC is passed for VM?

I'm using Ubuntu 10.04 Server image. Tests to load that image were conduced
with success, with command:
qemu -hda Ubuntu.img

The image runs without problem.

Thanks,

Erico.
