The issue I in some way hear in complaints is, that running as PVM guest (at least) people seem to have used for example "sda1" in the instance configuration and then relied on the device being called that way within the instance. Now it is suddenly called "xvde1". This is maybe a broken assumption in the first place, and not that hard to cope with (its just surprising and maybe breaks some automation). I mainly want to understand the reasoning, so I can explain it where I get asked. Thanks, Stefan
