Open Stack

I am actually hitting a similar issue with devstack setup on F20
I am able to spawn Nova instances and have setup keypair and sec-groups and
using those key and secgroup while spawning the instance

My instance boots up fine and has a 10.x.x.x IP.. I can get into the
instance usign VNC.. but cannot ping my host (On which VM is created) from
inside the instnace and vice versa. I see that sshd is running inside the
instnace and doing ssh root at localhost in the instnace works

So what else am I missing for the networking NOT to work ? ANy body has any
suggestions ?
