This change adds support for the SHELVED_OFFLOADED and (partly) VERIFY_RESIZE states. Shelved-offloaded instances don't have a hypervisor associated with them. VERIFY_RESIZE instances should still be running on their associated hypervisor. They are also present, but "shut off", on another hypervisor. Even with this change, the code still generates a warning about the instance being present on multiple hypervisors. Personally I find the warning quite useful, and I don't really know what to do about it. Maybe we should suppress the warning if the instance hasn't been in this state for long.

Nova folder
this folder contains scripts that are related to Nova
Compare Nova state to hypervisor state: nova-libvirt-compare.py
This retrieves all instances in a region (or all regions when called
with -a), then compares that with the libvirt domains running on all
hypervisor hosts in that region, and reports any differences.
Usage
usage: nova-libvirt-compare.py [-h] [-a] [-l REMOTE_USER]
[--no-note-incomplete]
[--blindly-trust-host-keys] [-p PROCESSES] [-v]
Check for inconsistent state between Nova DB and hypervisors
optional arguments:
-h, --help show this help message and exit
-a, --all-regions query all regions
-l REMOTE_USER, --remote-user REMOTE_USER
SSH remote username for connecting to hypervisors
--no-note-incomplete Don't report incomplete instances
--blindly-trust-host-keys
Accept all SSH host keys. This enables man-in-the-
middle attacks!
-p PROCESSES, --processes PROCESSES
Number of parallel processes connecting to hypervisors
-v, --verbose verbose
Example
$ ./nova-libvirt-compare.py
Hypervisor zhdk0062.zhdk.cloud.switch.ch should know about bd384f32-5e05-43a5-a66e-fc11693a733b, but doesn't
Instance ebd1c623-35c3-4385-998f-10a96ecfbcdf (state BUILD) has no hypervisor
