Hi,

But when I do this. It just don't work. Let me explain.

That's what it says the documentation. I understood that the instance is 
created with a private ip, so I start it with just one network in it. 
The private one.

And once it's started and working, I just assign it a public ( floating 
) ip. Horizon let me select the private ip interface.

When I reboot the instance it has two ip added but only one (the private 
one) is used in the instance. So where is the floating ip?

I supposed that it should create a second interface in my external 
bridge. But it's not. So how he hell this floating ip is used?


Sencond way I supposed it to work is create an instance with two nics. 
One on the private network, one on the public network. Then a floating 
ip will be assigned to public nic. But this is what it fails. And why I 
wrote the e-mail.

So if you can do both. What's the right way to do it. I suppose that 
both, but what I'm doing wrong?

Best regards,
