May anyone hear about cloudlet or openstack++? That is a VM platform based on the openstack kilo developed by CMU. And I encountered a difficulty about network connection in this.

My VM cannot be accessed from another physical machine(test by apache2), but the VM had network connection indeed. I can executed the commands Like apt-get update and upgrade in my VM.

What I think maybe wrong is floating-ip. When I did not associate the floating-ip, the VM network connection is well. As I associated the floating-ip, the VM became disconnection. Should I associate an IP address that is not being used? 

There are the commands I used to create network:

nova network-create myVM --fixed-range-v4 10.11.12.0/24 --fixed-cidr 10.11.12.0/24 --bridge virbr0--bridge-interface eth0

nova floating-ip-bulk-create 10.x.x.x(my IP address)/24

Is anything wrong? Is the 10.x.x.x address wrong because it is a private address?
