Hyper-V attach iscsi base volume failed due to WMI exception

Asked by ChangBo Guo(gcb)

Issue Description:
   I created a volume on RedHat6.3 with "volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver" and created a instance on HyPer-V (windows 2012), then tried to attach the volume to the instance ,but failed . It throwes Exception <x_wmi: Unexpected COM Error (-2147352567, 'Exception occurred.', (0, u'SWbemObjectEx', u'Generic failure ', None, 0, -2147217407), None)>

Test steps:

1. create a volume and boot a instance :
    cinder create 1 --display-name iscsi_volume1
     nova boot --image e73592aa-ea41-4d44-84df-2911483bacca --flavor 1 gcb_iscsi1

 2. check status
 [root@localhost /]# cinder list

iSCSI is a standard protocol, so I expect the same behaviour at least for a large subset of features between MS iSCSI, Linux tgt, Open-iSCSI, etc

Here's a pointer on the MS implementation: http://technet.microsoft.com/en-us/library/ee338476(v=ws.10).aspx
Wikipedia is as usual a good starting point: http://en.wikipedia.org/wiki/ISCSI
