Hi guys, It is fantastic that this is maybe the first mail in the list:) I am a newbie of deltacloud. I have setup the framework of deltacloud on my fedora 11 host, with mock as its default driver. And also I installed portal of deltacloud through which I can manage instances and images. But I`d like to konw if each Deltacloud framework instance could only have one driver(mock or rhev-m or ec2). In other words, if you want to work with multiple different clouds, is it compulsory that you have to start multiple framework instances, each of which has its own default driver(and the only driver)? BTW,could anybody give some information on how to get work with RHEV-M driver? It seems that neither of the READMEs of framework or portal has covered this. Thank you in advance. --Yuzhang
