When testing OpenStack in my local environment, downloading package or yum install takes a lot of time.
Thus, I enable squid in all nodes, by pointing http_proxy to a local squid server.

squid client works well, but nova cli fail.

So I tested this by:
- bringing up a new VM in a public cloud
- installing devstack
- verifying that I could boot an instance in devstack
- installing / configuring squid
- verified squid was working
- made python nova client requests
These requests appear in the squid log, and work for me.
Are there additional steps I need to duplicate this problem, or is it perhaps a local squid misconfiguration?
