Bug Description

I have created a VM,it came to ACTIVE and console log generated fine.
after that i have taken the snapshot of it,later when I checked the console log it is of 0 size.

$nova boot --image d80f7d2f-1d11-4364-8c1c-6a0791a6e15b --flavor 1 test

$ ls -l /opt/stack/data/nova/instances/instance-00000001/console.log
