Thank you Razique!

Out of nothing, all instances gets its IP automatically again, without even
restarting it... Have no idea about what had happened.

But, this is very weird, every time I restart a compute node, those network
problems appear... No idea about the source of this problem...

Tks again!

Best,
Thiago
