Open Stack

Hi,

I'm installing Openstack for the first time in three VMs following the 
doc in 
http://docs.openstack.org/icehouse/install-guide/install/yum/content/ch_overview.html

After adding the trove module I found out that I had a few different 
issues so I manually rolled back and un-installed trove.

Neutron was actually working fine until Trove came into the equation, 
but now the neutron server is not starting, even after removing it.

In my /var/log/neutron/server.log I get the below:



2014-07-31 15:28:23.205 12228 CRITICAL neutron [-] unable to access 
signing_dir /var/cache/trove

2014-07-31 15:28:23.205 12228 TRACE neutron ConfigurationError: unable 
to access signing_dir /var/cache/trove



I have checked all my configuration files that there are no references 
to the /var/cache/trove. I have actually commented out any reference to 
it but still pops out in the neutron log:

[root at controller ~]# grep -R "/var/cache/trove" /etc
/etc/cinder/api-paste.ini:#signing_dir = /var/cache/trove
/etc/trove/api-paste.ini:#signing_dir = /var/cache/trove


Is there any additional step I need to follow to completely remove 
trove from the server?

Any other ideas how where to look?

Cheers,

David
