I don't like this:

15: qg-d351f21a-08: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state 
UNKNOWN group default
     inet 192.168.122.193/24 <http://192.168.122.193/24> brd 
192.168.122.255 scope global qg-d351f21a-08
        valid_lft forever preferred_lft forever
     inet 192.168.122.194/32 <http://192.168.122.194/32> brd 
192.168.122.194 scope global qg-d351f21a-08
        valid_lft forever preferred_lft forever

Why you got two IPs on same interface with different netmasks?

I just rechecked it on our installations - it should not be happens.

Next: or this is a bug, or this is uncleaned network node (lesser bug), 
or someone messing with neutron.

Starts from neutron:

show ports for router:

neutron port-list --device-id=router-uuid-here
neutron floatingips-list
neutron net-list
neutron subnet-list
(trim to related only)

(and please mark again who is 'internet' and who is 'internal' ips, i'm 
kinda loosing in '192.168.*'.
