Public bug reported:

Description of problem:

The resize process fails and move the instance to a an 'error' state. 
The instance was created with the flavor: 
m2.small  | 2048      | 10   | 0         |      | 1     | 1.0         | True
and was resized to: 
m3.small  | 2048      | 10   | 10        | 2048 | 1     | 1.0         | True

the Horizon error message:

Error: Failed to launch instance "cirros": Please try again later

node IP> mkdir -p

How reproducible:
100%

Steps to Reproduce:
1. Launch an instance with the small flavor
2. create a flavor with ephemeral disk
3. resize the instance to the new flavor

Actual results:
The resize fail. the instance move to error state

Expected results:
the instance should be resized to the new flavor
