Public bug reported:

Hi 
I've just found a strange behavior. 

When booting from a volume I have found that nova sometimes will loose
the attached volume. My investigations lead me to the point that the
instance is too small for the image. But the first time I boot the image
from a volume (new) I can do it.

After first reboot it looses the ability to boot.

2014-01-23 21:59:35.547 2398 TRACE nova.openstack.common.rpc.amqp     raise exception.InstanceTypeDiskTooSmall()
2014-01-23 21:59:35.547 2398 TRACE nova.openstack.common.rpc.amqp InstanceTypeDiskTooSmall: Instance type's disk is too small for requested image.
2014-01-23 21:59:35.547 2398 TRACE nova.openstack.common.rpc.amqp 


I also found that the disk on the VM should be something like this:

/dev/disk/by-path/ip-172.16.0.119:3260-iscsi-iqn.2010-10.org.openstack:volume-137bc77b-c9e6-47ba-b2f5-c83f440a988b-lun-1
And when image is lost I found something like 

OSError: [Errno 2] No such file or directory:
'/var/lib/nova/instances/29c7b639-cb6e-4ea3-b913-2a84d518d1ed/disk'

That seems curious for me since the only thing that I see in horizon is
that the image cannot be launched.


I can reproduce this error in havana (ubuntu saucy) 100% time. 

Best regards,
