New subject: Change in vdsm[master]: Make HSM service self containted

Tuesday, 29 January 2013

Shu Ming has uploaded a new change for review.

Change subject: [WIP]Make HSM service self containted
......................................................................

[WIP]Make HSM service self containted

After moving the share files between common
VDSM service and HSM service to site package
directory, HSM service now can start up locally
only depending on site package files.  Also make
sure the original VDSM service can startup only
depending on the site package files.
