Just to avoid someone push this serie in its current state by mistake. This version is not stable on midway, DOM0 get easily stuck when I compile xen tools. I bisect quickly across the various version, and the V4 seems the last one which is stable (i.e not crash after a couple of hours of usage). Cheers, -- Julien Grall
