Isn't something like this generally sufficient for a shell script?

lspci -n | grep -q "5853:0001"
if [ $? -eq 0 ]; then
        # HVM domain
elif [ -d /proc/xen ]; then
        if grep -q "control_d" /proc/xen/capabilities; then
                # DOM0
        else
                # DOMU
        fi
else
        # Native
fi

It seems fairly reliable on ia64 for Xen 3.x.  Thanks,

        Alex
