Thanks.

Sounds like a config error.
What's the value of this variable in /etc/nova/nova.conf?
###### (ListOpt) A list of the glance api servers available to nova ([hostname|ip]:port)
# glance_api_servers="$glance_host:$glance_port"

I think you need to remove the http:// prefix from the above

This looks like a reasonable bug to file that would be trivial to fix.
Nova should be a bit more forgiving if the http prefix is given.

I'm not sure.
The error message isn't too bad.
Also it's generally best to limit input combinations.
What about 'https', trailing '/' etc.
Also maybe in future http might not be used,
which would involve config editing to support.
cheers,
Pádraig.
