yong sheng gong (gongysh) said : #1

please add
log-dir=/var/log/nova
debug=true
into nova.conf and see what's in the log files

and also enable the log for keystone.

Or we can start the nova binaries by console to see the output on console.

koolhead17 (koolhead17) said : #2

chown -R nova:nova /etc/nova

restart all services and it will work.

Havent (guestly) said : #3

to koolhead17: It still doesn't work.
to yong sheng gong: It doesn't print any log.

I checked the /var/log/nova/nova-network.log, it said:

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Lorin Hochstein (lorinh) said : #7

This error messages suggests that nova doesn't have sudo privileges. If you installed from packages on ubuntu, then add the following line to nova.conf:

root_helper=sudo nova-rootwrap

Aimon Bustardo (aimonb) said : #8

Correct solution is to remove the Defaults requiretty from /etc/sudoers.
