In your case, the actual storage does not really matter, it's more of a setup/functionality issue. I would recommend that you indeed get two machines, one for mgt server and one as hypervisor. For the networking requirements you need to read the documentation, and start with a basic zone. The guide you mentioned is only for the 4.0 version. Try to use the 4.1 version. Maybe you can patch the quick install guide so that it works for 4.1, that would be very much appreciated. Check some of the screencasts I did, this might help: http://www.youtube.com/playlist?list=PLb899uhkHRoZCRE00h_9CRgUSiHEgFDbC Also, at: http://jenkins.cloudstack.org/job/docs-4.3-clients-wrappers-guide/ I created some initial whirr documentation. -Sebastien > . >
