Hi all,

I use the trunk version of Nova, Quantum (with the OVS plugin) and Melange.
I created networks, everything seems to be right.

I have two questions :
- the first VM I boot takes always a wrong IP address (for instance
172.16.0.0). However, when I boot a second VM, this one takes a good
IP (for instance 172.16.0.2). Do you know why this can happened ?

- I have an error regarding an fixed IP not found. Effectively, when I
check the nova database, the fixed_ip table is empty but as I am using
quantum and melange and their tables seems to be nicely filled. Do you
have an idea about this issue ?
This is a copy/paste of the error:
