Open Stack

Hi guys, i am trying to use instance resize but i can't make it work. I
have a grizzly small cloud, with a controller node, 2 compute nodes and a
storage node. This is how i run the resize:

# nova --debug resize pruebas 102 --poll
Instance resizing... 0% complete
Instance resizing... 0% complete
Instance resizing... 0% complete
Instance resizing... 0% complete
Instance resizing... 0% complete
...
Instance resizing... 0% complete

Error resizing instance
#

I found this in nova-compute.log:

Any idea why i get this Timeout? I also have a similar problem when i try
to migrate instances. It seems to be related to rabbit, but i can't figure
it out.

Thanks!
