Subject Re: why we delete prmary storage pool every time when stopping vm?
Date Fri, 20 Dec 2013 01:05:01 GMT
I updated the CRs and assigned them to Marcus.

Since the issues are not related to the new iSCSI code specifically, I
think Marcus will have a good idea what's going on there.

In any event, if I can be of assistance, please let me know.

Thanks
