:Matt,

:You sure won't argue that UML isolation is inherently better than one that can be provided by a hypervisor. If the performance is the same, what are you gaining?
:
:Hypervisor while slow, allows treating a complete OS with all applications as a black box. Why would I choose UML over a hypervisor?
:
:I am not trying to say there cannot be a place for vkernel. [I don't even yet understand what is does or how.] However, as a hosting company, why would I choose UML over a hypervisor?
