Tur= ns out a few weeks ago when implementing a sysctl I must have accidentally = deleted the architecture specific syctl in the default case of the common s= ysctl. This leads to Xen quietly defaulting to a x86_32 CPU. Jan. CONFIDENTIALITY: The contents of this e-mail are confidential and intended = only for the above addressee(s).
