Remove the Hyper-V driver
Nova Hyper-V driver is not tested in OpenStack upstream and no maintianers. This driver has been marked as deprecated in Antelope release. It has dependency on the OpenStack Winstacker project which has been retired[1]. As discussed in vPTG[2], removing the HyperV driver, tests, and its config.

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:
|
||||
|
||||
2. iscsicli QAddTargetPortal <your_iSCSI_target>
|
||||
3. 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:
|
||||
|
||||
1. Fist of all create a volume
|
||||
2. 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".
