Hello,
I am a Folsom user, I have been using the "nova list" command for a
while until couple weeks ago.
That command use to work just fine and one day it just stopped working.
I can run the command but nothing will show up.
Here is the output of my command:
nova --debug list

I am getting a 200 from Keystone, so it's not an auth problem...
Do you have any clues about that one?
Weird,
I would check whether the instances appear in nova database.
In addition, I would also check that the instances really exist in the
compute nodes by: "virsh list -a" or/and "pgrep qemu" (will return a pid
per running instance).
More two dump questions:
Are you sure that the machine you're running that command is the nova
api machine (the api calls are to 127.0.0.1, local machine)?
Can you run the same curl command again but with .../servers instead of
../servers/details (run it first by "nova --debug list" to get a new
token, then run it manually with a changed uri/url)?
Thanks a lot!
Clément
