Hi all!!

We're currently experimenting an error that's it's pretty weird, the reason
it's that with another user same base image and same flavor we can resize
the instance but with another user with the same base image we cannot with
this error on the logs:

2015-04-21 22:03:37.700 4047516 WARNING nova.scheduler.utils

NoValidHost: No valid host was found.


In case that someone ask this options are already on all the nodes and the
controller:

allow_resize_to_same_host=True
allow_migrate_to_same_host=True

Boths are in the default section, as I said before the resize can be done
with other instances and with and instances with the same specs.

On the other hand we tried with both cli and dashboard and both user with
enought quota to do the resize and with all the nodes with ram and cpu for
the instance, as a said we already did it with an instance with the same
flavor, can anyone point us on how to do a more deep debug or any advice
about how to handle the error to do a the resize?


Thanks in advance
