This change is conceptually wrong. The pages balloon is allocating are unmanaged and they should be wired by definition. Alan and I are considering enforcing this (mandatory wired pages for unmanaged pages allocation) directly in the KPI. This in practice just seem an artifact to deal with scarce wired memory limit. I suggest that for the XEN case this limit gets bumped rather relying on similar type of hacks. Attilio -- Peace can only be achieved by understanding - A.
