Hi all,
I am trying to migrate a vm from Folsm version which using nova-network to Grizzly version which using quantum, I am using the following method:
step 1: snapshot the vm in the Folsm version 
step 2: upload the snapshot in the Grizzly version using glance 
step 3: launch the new image in the Grizzly version
the result is that the vm can start and the status is running,and it can get the fixed ip and the floating ip, but the network failed, I can't ping it from the outer world.
can anybody help me out?
thank you !
