Hi All,
We are experiencing a problem with our OpenStack Folsom installation
on Ubuntu 12.04, using nova-network: instances are NOT created, and
deleting instances in error state fails.
First of all: the installation was in "production" for almost one
year, and we didn't change anything. The only change made was updating
some packages from ubuntu and from ubuntu-cloud archives.
(PS: The following text is formatted as restructured text)
In details what happen is:
* The instance is created `Thu Oct 31 18:01:00 CET 2013`::

This backtrace does not seem to be relevant, as I've already seen
it in log of instances that started without problems.
* After a while, IPs are assigned to the instance. I don't see
anything in the ``nova-network.log``, but I can see the IPs in the
``nova list`` output. I also see the following errors in the compute

* After this, the instance is in ERROR state. If I delete it, it
usually only release the IPs, and only after a while, if I re-run
``nova delete``, it *sometimes* actually delete the instance.
This is driving me crazy, I don't really know where to look for
hints. I guess the problem is in the network node, but I can't
understand anything from the logs.
can someone help me with this?
Thank you in advance
