We are looking to start to set up our VM's with the following harddrive layout to get ahead of paravirtulization. c: (0:0) d: (1:0) e: (2:0) etc. We are currently setting drives up like this: c: (0:0) d:(0:1) e:(0:2) I have found that the upgrade at the VM level is a hardware upgrade and a new scsi adapter will be available to take advantage of the "PV" technology. Is there any harm in setting our partitions up like this with our current v3.5 environment and will this layout provide the PV benefits that are available?
