Xen users - Nov 2014 - libvirt <emulator> /usr/local/lib/xen/bin/qemu-dm <emulator> did not work on xen-4.4

I run a VM on xen-4.4.0  , libvirt-1.2.9

ubuntu.xml

<domain type='xen'>
    <name>xubuntu12.xml</name>
    <memory>4131072</memory>
    <currentMemory>4131072</currentMemory>
    <vcpu>1</vcpu>
    <os>
        <type arch='x86_64' >hvm</type>
        <loader>/usr/local/lib/xen/boot/hvmloader</loader>
        <boot dev='hd'/>
    </os>

        <emulator>/usr/local/lib/xen/bin/qemu-dm</emulator>
        <disk type='file'>
            <source
file='/home/rip/Documents/xubuntu_12_x64.img'/>
            <target dev='hda'/>
        </disk>
        <interface type='bridge'>
            <source bridge='xenbr0'/>
        </interface>
        <input type='tablet' bus='usb'/>
        <input type='mouse' bus='ps2'/>
        <graphics type='vnc' port='70001'
autoport='no' listen='0.0.0.0'/>
    </devices>
</domain>


But,  I run "ps aux | grep xen"  , I found it was qemu-system-i386
work.

/usr/local/lib/xen/bin/qemu-system-i386 -xen-domid 5 -chardev
socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-5,server,nowait -mon
chardev=libxl-cmd,mode=control -nodefaults -name xubuntu12_x64 -vnc

-boot order=dc -usb -usbdevice tablet -device
rtl8139,id=nic0,netdev=net0,mac=00:16:3e:65:48:5d -netdev
type=tap,id=net0,ifname=vif5.0-emu,script=no,downscript=no -machine pc,accel=xen
-m 4088 -drive
file=/home/rip/Documents/xubuntu_12_x64.img,if=ide,index=0,media=disk,format=raw,cache=writeback
