Bug Description

Hi all,

I'm having an issue configuring an LXC/libvirt compute node with nova on Icehouse.
I followed the instructions on your configuration manual here :
http://docs.openstack.org/trunk/config-reference/content/lxc.html
but I have this error :

I also know that LXC/libvirt is known to be deprecated on Icehouse as said on the hypervisor matrix so I'm confused as it is still in the configuration manual.

I would like to know if there is a way to get rid of this error or if it's purely impossible to use LXC/libvirt on Icehouse.

Regards,
Vanzaghi Axel

Hi again,

maybe more information should be welcomed.

I'm running on debian Jessie so the version of libvirt is 1.2.1. Maybe the probleme is from here as the Wheezy libvirt version is 0.9.12.

thanks for answer,
Vanzaghie Axel

Hi again again,

I dowgraded my libvirt-bin (dowgrade libvirt0, libnetcf1 before and python-libvirt after) and it works.

Sorry for disturbing you.

Thanks for reporting, but I can't determine if this is a documentation bug. Have you tried asking on http://ask.openstack.org?

Thank for you answer,

as I said, I solved it by myself bringing back wheezy libvirt packages, but maybe you'll have to be aware of this bug if you plan to support jessie in the future.

Anne, I think this a wider question for the Nova team - it seems like it's a symptom of the fact that we only test a very specific (old) version of Libvirt in the gate. This is a well known issue though.
