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)?
