Looks like something is already binding on 8774 (probably nova-api :)  )
What does  lsof -i :8774 say?  Then see what process is running.

For example:

arosen@arosen-desktop:~$ lsof -i :8774
COMMAND   PID   USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
python  13936 arosen    6u  IPv4 32808940      0t0  TCP *:8774 (LISTEN)
python  13945 arosen    6u  IPv4 32808940      0t0  TCP *:8774 (LISTEN)
python  13946 arosen    6u  IPv4 32808940      0t0  TCP *:8774 (LISTEN)
arosen@arosen-desktop:~$ ps -eaf | grep 13936
arosen    4822 14986  0 10:27 pts/62   00:00:00 grep --color=auto 13936
