Reporting the disk_available_least field can help in making sure the scheduler doesn't pick a host that cannot fit a specific flavor's disk. The reported local_gb_used is calculated based on the instances spawned by nova on a certain compute node, and might not reflect the actual reality, especially on shared storage scenarios.

Hyper-V Volumes Management
To enable the volume features, the first thing that needs to be done is to enable the iSCSI service on the Windows compute nodes and set it to start automatically.
sc config msiscsi start= auto net start msiscsi
In Windows Server 2012, it's important to execute the following commands to prevent having the volumes being online by default:
diskpart san policy=OfflineAll exit
How to check if your iSCSI configuration is working properly:
On your OpenStack controller:
1. Create a volume with e.g. "nova volume-create 1" and note the generated volume id
On Windows:
- iscsicli QAddTargetPortal <your_iSCSI_target>
- iscsicli ListTargets
The output should contain the iqn related to your volume: iqn.2010-10.org.openstack:volume-<volume_id>
How to test Boot from volume in Hyper-V from the OpenStack dashboard:
- Fist of all create a volume
- Get the volume ID of the created volume
3. Upload and untar to the Cloud controller the next VHD image: http://dev.opennebula.org/attachments/download/482/ttylinux.vhd.gz 4. sudo dd if=/path/to/vhdfileofstep3 of=/dev/nova-volumes/volume-XXXXX <- Related to the ID of step 2 5. Launch an instance from any image (this is not important because we are just booting from a volume) from the dashboard, and don't forget to select boot from volume and select the volume created in step2. Important: Device name must be "vda".
