During the havana cycle it was discovered that eventlet
monkey patching of greendns broke ipv6.
https://bugs.launchpad.net/nova/+bug/1164822
Since then nova has been disabling eventlet monkey patching
of greendns. Eventlet addressed the ipv6 limitation in v0.17
with the introduction of python 3 support in 2015. Nova
however continued to disable it, which can result i slow dns
queries blocking the entire nova api or other binary
because socket.getaddrinfo becomes a blocking call into glibc
see: https://bugs.launchpad.net/nova/+bug/1964149 for
more details.
