Foreword, all of this is on essex.

I'm trying to deploy a virtual machine image I've made myself following a
procedure similar to the one outlined here:
used virt-manager and x11 forwarding instead of VNC to connect to the

However, when I attempt to boot this image using the following command: (6
is a custom flavor)
nova boot --poll --flavor 6 --image <img id> --key_name my_key
--availability_zone=zone1 t1dbvm
it will say "Error building instance"

on the compute node I'm seeing this:

Then a bit further down:
2013-01-17 11:58:41 TRACE nova.rpc.amqp IOError: [Errno 28] No space left
on device
2013-01-17 11:58:41 TRACE nova.rpc.amqp

I'm wondering if my root partition is too small. The image I'm trying to
deploy is 10GB but I only have ~7.6GB available on root, (but 400GB+ on

Any thoughts? I know this VM image is bootable, I can boot it manually
using virt-manager.

PS: I don't know if it's related but in the nova-compute.log I'm also
seeing "Instance found in database but not known by hypervisor. Setting
power to NOSTATE."

Help is appreciated, thanks very much in advance.
