[one-users] instance running without IP

[song]

Hi everyone:

I am a newbie to OPENNEBULA! I just try opennebula 2 days ago.

Now I followed some blog to setup my environment, It seems there's
nothing going down,only instance running without IP ,I have create
virtual network resources by assign network and mask like :192.168.0.0
and 255.255.255.0.But every time I run an instance it won't fetch an IP
from pool,

Can anyone help?

Any help will be appreciated.
