Public bug reported:

when I run : 
#nova live-migration 90e9804e-4e93-446d-ade3-9143421ee5b9 devstack3

I get this :

ERROR: Unable to migrate instance (72939da1-1a41-4a2a-8bf4-1136008ffa26)
to current host (devstack3). (HTTP 400) (Request-ID: req-
3e9b5036-1072-4553-bac5-8f02d9659611)

but the instance gets migrated

and when I ask the instance to get back to its previous host :

#nova live-migration 90e9804e-4e93-446d-ade3-9143421ee5b9 devstack

no message is return to the CLI but the instance is not migrated.
moreover, on devstack3, I see this error : 

2014-02-07 16:14:06.824 16304 ERROR nova.virt.libvirt.driver [-]
[instance: 72939da1-1a41-4a2a-8bf4-1136008ffa26] Live Migration failure:
internal error Attempt to migrate guest to the same host e533b2bd-85bc-
71de-e788-a903d6fccfa4

I will try to dig deeper ASAP
