Comment 1 for bug 1498867

Summary:
1. Nova doesn’t use Memcached in MOS 7.0 – it isn’t configured in nova.conf to use memcached
2. Keystone uses for Memcached 1 sec timeout and 30 sec dead_retry
3. The dead_retry is set to 30 sec due to FUEL requirements, it doesn’t like to wait for 300 sec at installation time

What need to be done:
1. Validate that Nova (keystone client) doesn’t use memcached
2. Validate that long delay (40 sec) comes from interactions with Keystone and it isn’t internal to Nova client
