<p>I am getting a 200 from Keystone, so it's not an auth
problem...<br>
Do you have any clues about that one?</p>
</div>

Weird, <br>
<br>
I would check whether the instances appear in nova database.<br>
<br>
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).<br>
<br>
More two dump questions:<br>
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)?<br>
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)?<br>
<br>
