For HVM Xen, state that ACPI and APIC can be turned on and off.
I'm pretty sure that in recent versions of Xen, both of these features are unconditionally enabled.
From testing this a little (after fighting silly fights with rawhide and xen config files) with an FC6 i386 guest on an x86_64 hypervisor:
* In RHEL5 (xen 3.0.3), for both plain xen config files + xm create and libvirt XML + virsh create: <acpi default='off' toggle='yes'/> <apic default='off' toggle='yes'/> <pae default='off' toggle='yes'/> * In rawhide (3.1.0) using xen config files and xm create: <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> <pae default='on' toggle='yes'/> * In rawhide (3.1.0) using libvirt XML and virsh create: <acpi default='off' toggle='yes'/> <apic default='on' toggle='no'/> <pae default='off' toggle='yes'/> We really only care about the libvirt XML part, for which only apic has differences between 3.0.3 and 3.1.0. I'll update the patches to take the above into account, David
