I modify the libvirt /src/qemu_conf.c. Add the arch ia64 into the static const struct qemu_arch_info const arch_info_hvm[] = {} as berrange said. So the libvirt passing -M ia64. But the kvm binary only experts '-M itanium'. So i replaced the ia64 by itanium in the file /src/qemu_conf.c. Then the virt-manager finally could work on the arch of Itanium. Thank you for your help.
