Error on nova compute on Power

[Victor Estival]

I'm trying to deploy OpenStack in a Power 8 server on a single node.

I've created 1 VM for MAAS, 1 VM for juju bootstrap and 4 VMs to use them as compute, ceph and to hold all the OpenStack services.

I've deployed OpenStack and everything seemed to work fine, however, I don't see any hypervisor. When I check into the nova logs I find:

2015-02-06 11:36:25.499 54731 TRACE nova.openstack.common.threadgroup libvirtError: XML error: Missing CPU model name

Can you tell us about your environment, openstack release, software level etc?
Also, provide libvirt version (dpkg --list | grep libvirt) and cpu_map.xml file (/usr/share/libvirt/cpu_map.xml or something like that)?

[Victor Estival (victor-estival-l)]

Environment:
Power 8 server with 3 hard disks running Power KVM 2.1
Ubuntu 14.04 on Power
OpenStack version: Icehouse

Everything deployed with juju and stable charms from jujucharms.com

Extra info

ubuntu@compute02:~$ dpkg --list | grep libvirt
ii libvirt-bin 1.2.2-0ubuntu13.1.9 ppc64el programs for the libvirt library
ii libvirt0 1.2.2-0ubuntu13.1.9 ppc64el library for interfacing with different virtualization systems
ii nova-compute-libvirt 1:2014.1.3-0ubuntu2 all OpenStack Compute - compute node libvirt support
ii python-libvirt 1.2.2-0ubuntu2 ppc64el libvirt Python bindings

Here is the output for /usr/share/libvirt/cpu_map.xml

Let me know what other info do you need

[Erhan Ekici (erhan-ekici)]

can you send or put somewhere your whole compute log and nova*.conf files? Thxs.

[Victor Estival (victor-estival-l)]

Please, find the output of more /etc/init/nova-compute.conf here:

[Victor Estival (victor-estival-l)]

Do you have update or do you need any extra info?

[Randall Ross (randall)]

Has there been any further analysis on this bug?

[Victor Estival (victor-estival-l)]

I haven't seen any. If anyone needs some more info just ask

Is this still a problem in juno or kilo code?

[Victor Estival (victor-estival-l)]

Is it in Juno, I haven't try on Kilo yet

[Mauro S M Rodrigues (maurorodrigues)]

Hi I've been looking around and I'm pretty confident that it's the same bug https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1418221 - which is fixed on upstream libvirt 1.2.13 (https://libvirt.org/news.html "PowerPC : Forbid NULL CPU model with 'host-model' mode. (Prerna Saxena)" ) and partially addressed, per comment https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1418221/comments/7 on vivid.
I just left a comment asking them to backport Prerna's patch to utopic.

[Victor Estival (victor-estival-l)]

Hello:

So, in order to solve it... which versions of Ubuntu and OpenStack should I
use?

Thanks

[Mauro S M Rodrigues (maurorodrigues)]

I would go with ubuntu 15.04, but I've asked for a backport in utopic too, soon should be available.
openstack any version, although I haven't tested the latest kilo rc

[Victor Estival (victor-estival-l)]

Hello:

that's great! thanks

Best regards,

[Davanum Srinivas (DIMS) (dims-v)]

Does not look like there's a code fix in Nova. Right?

[Victor Estival (victor-estival-l)]

Not yet... I wil try it next week and I'll let you know it goes
