Open Stack

Hello,

I'm trying to test out live migration but it fails with rcp version error,
look below

from nova-api.log
2012-07-23 20:07:49 TRACE nova.api.openstack.compute.contrib.admin_actions
RemoteError: Remote error: RemoteError Remote error: UnsupportedRpcVersion
Specified RPC version, 1.2, not supported by this endpoint.

from nova-scheduler.log
2012-07-23 20:07:49 TRACE nova.openstack.common.rpc.amqp RemoteError:
Remote error: UnsupportedRpcVersion Specified RPC version, 1.2, not
supported by this endpoint.

I'm using trunk latest trunk version (few days old).

I'm initiating live migration with the following command:
nova --debug live-migration e10f7e21-a5a5-496d-940c-6ee745e7b048 compute2

the debug output of the failure that I get in return:

As I understand, then I need to set the RPC version somewhere, but where? I
checked the config options, the only item that have something appropriate
is the option for nova command with
--os_compute_api_version, but the same errors remain when RPC API version
is changed. After checking the source, I found that
'nova/compute/rpcapi.py', have default version set to '1.0'.

Can you please shed some light about this issue?
