ChangBo Guo(gcb) 69fef14509 Performance: leverage dict comprehension in PEP-0274 
PEP-0274 introduced dict comprehensions to replace dict constructor
with a sequence of length-2 sequences, these are benefits copied
from [1]:
  The dictionary constructor approach has two distinct disadvantages
  from the proposed syntax though.  First, it isn't as legible as a
  dict comprehension.  Second, it forces the programmer to create an
  in-core list object first, which could be expensive.
Nova dropped python 2.6 support, we can leverage this now.
There is deep dive about PEP-0274[2] and basic tests about
performance[3].
Note: This commit doesn't handle dict constructor with kwagrs.
This commit also adds a hacking rule.

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:

  1. iscsicli QAddTargetPortal <your_iSCSI_target>
  2. 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".
