Instances can start on the first nova node (controller) fine.

I am having problems with the second nova computing node. 
"nova-manage service list" shows "nova-compute" have smilies on both nodes. 
"euca-describe-images" shows the correct images. 
however when I launch an instance, nova's compute log shows 

TRACE nova.rpc.amqp   File "/usr/lib/python2.7/site-packages/nova/image/", line 86, in pick_glance_api_server
TRACE nova.rpc.amqp     host, port_str = host_port.split(':')
TRACE nova.rpc.amqp ValueError: too many values to unpack
TRACE nova.rpc.amqp

This is on a fedora 16 environment. Both computers have the same rpm packages.

Thanks in advance.
