Generic driver jobs are failing because of timeouts when
establishing the initial ssh connection from manila-share
to the service VM.
Bump up the default value of the connection timeout for paramiko
client and also set the banner timeout since the failure occurred
during banner exchange. Set the two timeouts to the same value
for now. This ensures that the connection timeout is at least as
long as the banner timeout and there is no current need in manila
to control these independently.
This is more of a workaround than a real fix since a real fix
would remove the delay during banner exchange. I suspect that
the real fix will need to be in neutron/ovs though.
