I got the impression that:- * i386 hypervisor support is a key use of Xen-4.1. * PV mode used more in older installs. I definitely think there is a case for supporting i386 hypervisor for PV guests, even if HVM may become unsupportable (e.g. also due to QEMU patching, though apparently QEMU could be swapped for newer more supportable version without too much trouble). --Simon
