Open Stack

Hi,

Thanks for your reply. Can I kindly know should I upgrade or downgrade the nova version?

Best regards,

Hi,

I also noticed that Openstack can be pretty picky about versions, at least with 2013.2.XXX.
Make sure the controller and compute nodes run the exact same versions.

The python neutron packages on the compute nodes also need to be the correct version.
Best would be to have just one version in your local repositorie or use puppet/chef/whatever ensure => versionxxxx for this.

Cheers,
