Subject Re: CS 4.0.0 - vpc deployment - why tier network limited to 200mb/s ?
Date Wed, 17 Apr 2013 18:14:38 GMT
I've located the detailed article on how to setup the network throttling
in cloudStack:

http://support.citrix.com/article/CTX132019


The approaches base on the Network type (Guest,Public,Control) and vmType
(VR/UserVm/SSVM)

We might need to add it to Apache Wiki.
