The descriptions of certain KVM related kernel parameters can be ambiguous and confusing. They state 'Disable ...,' which implies that setting them to 1 would disable the associated features or options, when in fact the opposite is true. This commit addresses this issue by revising the descriptions of these parameters to make their intended behavior clear.
