Open Stack

Hi All

I am a biginner in Openstack
I build a multi-node OpenStack platform (installed via Devstack) with two
types machine as compute (x86_64 and ARM A15), control/network/storage
server in the same x64 server.
I can launch a instance in x86_64 machine and work fine. It run
cirros-0.3.4-x86_64-uec success
In same local.conf,I  launch instance in ARM base machine use
cirros-0.3.4-arm-uec,but start failed and I found error message in
/opt/stack/logs/n-cond.log like below message.
