Subject RE: [ACS41][DISCUSS] Adding support for VMware dvSwitch
Date Wed, 02 Jan 2013 05:03:28 GMT
I have created an initial draft of the FS here,  
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Integration+of+CloudStack+with+VMware+DVS
I'll keep updating it based on discussion and comments.

Regards,
Sateesh
