Still can not work, I got:
(XEN) (GUEST: 6) HVM Loader
(XEN) (GUEST: 6) Detected Xen v3.0
(XEN) (GUEST: 6) Loading ROMBIOS ...
(XEN) (file=hvm.c, line=596) Bad HVM op 1222980.
(XEN) (GUEST: 6) hypercall_hvm_op returned error: 38
(XEN) (GUEST: 6) Loading Cirrus VGABIOS ...
(XEN) (GUEST: 6) Loading VMXAssist ...
(XEN) (GUEST: 6) VMX go ...

Maybe caused by the hypercall page
