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,
