RE: [Xen-devel] Genapic in 32-bit Dom0 (Was : More Problems booting32-bit Domain 0 on ES7000 x86_64)

It won''t pick up clustered apic, for example. thanks, -chris _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
