[Chmouel Boudjnah <chmouel@xxxxxxxxxxx>]

Public bug reported:


I have just done a fresh install using the package from latest nova-core ppa :

chmouel@chmoutest:~$ dpkg-query --showformat='${Package}-${Version}\n' -W '*nova*'
nova-api-0.9.1~r325-0ubuntu0ppa1~lucid1
nova-common-0.9.1~r325-0ubuntu0ppa1~lucid1
nova-compute-0.9.1~r325-0ubuntu0ppa1~lucid1
nova-objectstore-0.9.1~r325-0ubuntu0ppa1~lucid1
nova-volume-0.9.1~r325-0ubuntu0ppa1~lucid1
python-nova-0.9.1~r325-0ubuntu0ppa1~lucid1

I am running those command on a fresh install :

nova-manage user admin ant
nova-manage project create antproj ant
nova-manage project zip antproj ant
unzip nova.zip

and this is what I am getting in the logs (there is two of them!),
things seems to work still afterward :

nova-compute.log:
