Open Stack

Remo us right,

Do a test here,

On compute1

#su - nova
#touch `hostname.dat`
#scp -p `hostname.dat` compute2:/var/lib/nova/instances/

On compute2:

#su - nova
#touch `hostname.dat`
#scp -p `hostname.dat` compute1:/var/lib/nova/instances/

I don't remember exact username for nova user.
